ArmCpuLib is never used anywhere, and is about to be removed. So remove
any references from our .DSC files.

In this patch, the ACPI protocol / driver chain is enabled dynamically,
when appropriate. This is being done in one larger patch, because
ArmVirt.dsc.inc, where AcpiTableDxe is built, is used by all the platform
DSCs.
No change in behavior should be observable after this patch on any
ArmVirtPkg platform.

The various ArmLib flavors are identical in practice, and a new
ArmBaseLib has been introduced that can replace all of them. So replace
all occurrences with ArmBaseLib.

The clang developers have made a backward incompatible change to the
command line arguments, and have replaced '-mllvm -arm-use-movt=0'
with '-mno-movt'. This does not matter for most ARM platforms, and
therefore it has been removed from the default CLANG35/ARM CC flags
in patch 1c63516075b3 ("BaseTools CLANG35: drop problematic use-movt
and save-temps options"), but as it turns out, the relocatable PrePi
implementation used by ArmVirtQemuKernel and ArmVirtXen will fail to
build if it contains MOVT/MOVW pairs, due to the fact that these are
not runtime relocatable under ELF.
Since they are runtime relocatable under PE/COFF, and GenFw does the
right thing when encountering them, selectively controlling their
use is more appropriate than disabling them altogether. Therefore,
this patch adds the -mno-movt argument only for the platforms that
use the relocatable PrePi, and only for the module types that may
be pulled into its build.
In addition, switch to the SEC type version of ArmLib, so that
the relocatable PrePi only depends on BASE and SEC type libraries.

Switch all users of ArmLib that depend on the MMU routines to the new,
separate ArmMmuLib. This needs to occur in one go, since the MMU
routines are removed from ArmLib build at the same time, to prevent
conflicting symbols.

Now that the only functionality that remains in VirtFdtDxe is enumerating
the respective virtual I/O buses, it no longer makes sense to have a driver
that is shared between Xen domU and QEMU. So move the Xen I/O DT node
handling to a new driver, and update ArmVirtXen to switch to it.

Now that the PCI host bridge driver parses the DT node that describes
the PCI host bridge directly via the FDT client protocol, we can drop the
handling from VirtFdtDxe completely.
This means some PCI related PCDs are no longer set, such as PcdPciBusMin,
PcdPciBusMax, PcdPciIoBase, PcdPciIoSize, PcdPciIoTranslation,
PcdPciMmio32Base and PcdPciMmio32Size. Since these PCDs are specific to
ARM (and declared in ArmPlatformPkg), and not used anywhere else by the
ArmVirtPkg platforms, we can simply stop populating them, and drop all
references to them.
It also means that we can no longer rely on PcdPciDisableBusEnumeration
to be set before it is consumed by PciBusDxe and QemuFwCfgAcpiPlatformDxe,
so make those depend on FdtPciPcdProducerLib explicitly via NULL library
class resolution.

Remove the handling of the fw_cfg DT node from VirtFdtDxe now that the
fw_cfg client library has been moved to the FDT client protocol, and no
longer relies on VirtFdtDxe to pass this information via dynamic PCDs.
Since the PCDs in question are now no longer used, remove them from the
various DEC and DSC files as well.

Move to the new dedicated ArmVirtTimerFdtClientLib to populate the
various timer related PCDs at driver load time rather than relying on
VirtFdtDxe to do it. Since ArmPkg/TimerDxe is the only consumer of these
PCDs, which is the DXE driver ArmVirtTimerFdtClientLib is intended to
complement, this conversion is guaranteed to be safe.

The PcdDxe dynamic PCD driver is dispatched explicitly via an 'A PRIORI'
declaration in the platform DSC. Without that declaration, the DXE driver
can never be dispatched since it transitively (via DxePcdLib) depends on
protocols it produces itself. So use the NULL PcdLib explicitly only for
this driver.

This adds ARM support to the ArmVirtXen platform. As is the case for
AARCH64, the ARM port adheres to the ARM Linux boot protocol, i.e.,
it expects the address of a DTB describing the platform to be passed
in r2, and relocates itself at runtime to the actual load time memory
offset.

Beyond just changing the directly related lines in the FDF and DSC files,
we have to adapt the EarlyFdtPL011SerialPortLib and FdtPL011SerialPortLib
instances as well, in the same patch. This is because the EmbeddedPkg
driver expects the SerialPortSetAttributes(),
SerialPortSetControl() and SerialPortGetControl() functions from
SerialPortExtLib, while the MdeModulePkg driver expects them from
SerialPortLib itself.
We cannot implement these functions in ArmVirtPkg's SerialPortLib
instances *before* flipping the driver, because it would cause double
function definitions in the EmbeddedPkg driver. We also can't implement
the functions *after* flipping the driver, because it would cause
unresolved function references in the MdeModulePkg driver. Therefore
we have to implement the functions simultaneously with the driver
replacement.

A DMA-like transfer interface has recently been implemented in QEMU for
fw-cfg. For ARM and AARCH64 virtual machines, the binding prescribes a new
8-byte wide register at offset 0x10 in the register block. Make VirtFdtDxe
expose this register if it is present.
Please see "docs/specs/fw_cfg.txt" in the QEMU tree for more information.
