This patch generalizes the approach previously used for ARM32
TTB_SUBTABLES to "auto-detect" whether a certain region was defined in
memlayout.ld. This allows us to get rid of the explicit Kconfig for the
TIMESTAMP region, reducing configuration redundancy and avoiding
confusion when setting up future boards.
(Removing armv4/bootblock_simple.c because it references this Kconfig
and it is a dead file that I just forgot to remove in CL:12076.)

This patch removes the old arm64/stage_entry.S code that was too
specific to the Tegra SoC boot flow, and replaces it with code that
hides the peculiarities of switching to a different CPU/arch in ramstage
in the Tegra SoC directories.

The existing arm64 architecture code has been developed for the Tegra132
and Tegra210 SoCs, which only start their ARM64 cores in ramstage. It
interweaves the stage entry point with code that initializes a CPU (and
should not be run again if that CPU already ran a previous stage). It
also still contains some vestiges of SMP/secmon support (such as setting
up stacks in the BSS instead of using the stage-peristent one from
memlayout).
This patch splits those functions apart and makes the code layout
similar to how things work on ARM32. The default stage_entry() symbol is
a no-op wrapper that just calls main() for the current stage, for the
normal case where a stage ran on the same core as the last one. It can
be overridden by SoC code to support special cases like Tegra.
The CPU initialization code is split out into armv8/cpu.S (similar to
what arm_init_caches() does for ARM32) and called by the default
bootblock entry code. SoCs where a CPU starts up in a later stage can
call the same code from a stage_entry() override instead.
The Tegra132 and Tegra210 code is not touched by this patch to make it
easier to review and validate. A follow-up patch will bring those SoCs
in line with the model.

When we first added ARM support to coreboot, it was clear that the
bootblock would need to do vastly different tasks than on x86, so we
moved its main logic under arch/. Now that we have several more
architectures, it turns out (as with so many things lately) that x86 is
really the odd one out, and all the others are trying to do pretty much
the same thing. This has already caused maintenance issues as the ARM32
bootblock developed and less-mature architectures were left behind with
old cruft.
This patch tries to address that problem by centralizing that logic
under lib/ for use by all architectures/SoCs that don't explicitly
opt-out (with the slightly adapted existing BOOTBLOCK_CUSTOM option).
This works great out of the box for ARM32 and ARM64. It could probably
be easily applied to MIPS and RISCV as well, but I don't have any of
those boards to test so I'll mark them as BOOTBLOCK_CUSTOM for now and
leave that for later cleanup.
