Replace the PMU compatible string "arm,armv8-pmuv3" with the more
precise "arm,cortex-a53-pmu", potentially making more event types
available.

As reported by Kojima-san, the PHY reference clock value we use in our
ACPI and DT descriptions is out of sync with the hardware. Replace
125 MHz with 250 MHz throughout.

The ACPI/Linux code does not cope very well with I/O BAR windows that
involve type translation and address translation. In particular, the
secondary I/O window we implement on SynQuacer:
I/O 0x10000 ... 0x1ffff -> 0x77f00000
is misinterpreted by Linux, and results in the MMIO range starting at
0x77f10000 to be mapped for I/O port access to this range.
This can be mitigated by using the same bus range for I/O port access
on both RCs., i.e., [0x0 ... 0xffff]. This configuration can be represented
using both DT and ACPI, and will work as expected in Linux.
Now that the generic PCI host bridge driver has gained support for address
translation, we can actually support this configuration seamlessly in UEFI
as well, by applying an offset to the second I/O window to make it appear
adjacent to the first one in the CPU view of the I/O space.

Add a node for the I2C controller #1 to the device tree so the OS

On our SynQuacer based platform, power state handling and other
low-level duties are handled by the secure firmware, not by the
OS, so remove the various MHU/SCPI related nodes from the device

Implement support for the SynQuacer eMMC controller. This involves an
implementation of the SD/MMC override protocol to handle a couple of
quirks that would otherwise prevent this IP from being driven by the
generic SDHCI driver.
Also, add a HII page to the PlatformDxe driver that allows eMMC support
to be enabled, and wire it up for both DeveloperBox and EVB.

Even though the ARM ARM quite clearly states that the CNTFRQ field of
each MMIO timer frame should be a read-only alias of the CNTFRQ field
of the base frame, the SynQuacer SoC implements it as a register that
is programmable separately.
So let's program it from the hardware rather than overriding the
frequency using a DT property.

The upstream version of the Linux NETSEC driver expects the PHY DT
node to appear under a MDIO subnode, so fix this in the device tree.
Fix the node name as well, this should be 'ethernet' not 'netsec',
and add a clock-names property describing the single clock reference
as 'phy_ref_clk'.
Also, move the PHY subnode into the per-platform .dts file so we can
set the unit address in the node name. This is necessary because recent
versions of the DT compiler are more finicky about this.

Align the UART DT nodes:
- use 'uart' not 'fuart' as node name for the second serial port
- create an alias 'serial1' for the second serial port
- use UART clock reference instead of hardcoded frequency
- split 'clocks' property into 1 cell per phandle

In order to be able to use UART #0 on the DeveloperBox's 96boards low
speed connector, expose it to the OS by adding a node to the device
tree. This requires a CM3 firmware build that makes the SCP detach
from the serial port after boot.

As it turns out, it is surprisingly easy to configure both the NETSEC
and eMMC devices as cache coherent for DMA, given that they are both
behind the same SMMU which is already configured in passthrough mode
by the firmware running on the SCP.
So update the static SMMU configuration to make memory accesses performed
by these devices inner shareable inner/outer writeback cacheable, which
makes them cache coherent with the CPUs.
