Until PSCI is functional the other core still needs to be
brought up in the kernel. The kernel boots these cpus with
the spin table which is just an address in memory to monitor

Instead of defining the stacks by Kconfig options include
the stack sizes for all the CPUs including each of their
exception stacks. This allows for providing each CPU
on startup a stack to work with.
Note: this currently inherits CONFIG_STACK_SIZE from x86 because
of the Kconfig mess of options not being guarded.

Provide a common entry point arm64 cores coming out of reset. Also,
take into account CONFIG_ARM64_CPUS_START_IN_ELx to set the
correct SCTLR_ELx register. The SCR_EL3 initialization was removed
as that can be done in policy code in C later. Part of this refactor
allows for greater code reuse for the secure monitor.

2. the stack isn't necessarily CONFIG_STACK_SIZE bytes.

In order to access secure device register space the cpu
needs to have the page tables marked as secure memory. In
addition the page tables need to live within secure memory
otherwise the accesses default to non-secure.
Therefore move the page tables to the trustzone region. Remove
the TTB_* config options as well as removing the TTB reservations
from coreboot's resource list.

Tegra132 has 2 different paths for booting and resuming from
sleep. The boot path uses the typical bootblock, romstage,
and ramstage. However, the resume path is completely orthogonal.
cbmem_initialize() attempts to recover the cbmem area, but
that functionality should not be used from romstage because
tegra132 is by definition in a fresh boot if it is executing
romstage. Therefore, use cbmem_initialize_empty() so that cbmem
is always initialized from scratch on each boot.

This was a merge error when I was pulling in some of the
code into this file I put it after the read of CAP2 but
before it is modified and written back. In the end the
DEVSLP bits are getting set/cleared that need to but the
other bits in the register may be wrong. Also when enabling
devslp set the devslp-present bit in each enabled port.
Also remove much of the 0:1f.2@0x98 setup and the attempt
to write (the write once) CAP register that is already
being written in the reference code.

In order to prevent possible TPM lockout due to PLTRST assertion
shortly after powering up add a small delay before the reset.
This will affect cold power up only, reboot/resume/warmboot will
all have the flex ratio locked already so this reset is unneeded.
BUG=chrome-os-partner:29859
BRANCH=None
TEST=build and boot on samus. I tried unsuccessfully to trigger the
TPM lockout, but I was not able to do that consistently without this
patch so it is unknown yet whether this is 100% effective.
