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.

In order to have a proper runtime-modifyable page table API (e.g. to
remap DRAM after it was intialized), we need to remove any external
bookkeeping kept in global variables (which do not persist across
stages) from the MMU code. This patch implements this in a similar way
as it has recently been done for ARM32 (marking free table slots with a
special sentinel value in the first PTE that cannot occur as part of a
normal page table).
Since this requires the page table buffer to be known at compile-time,
we have to remove the option of passing it to mmu_init() at runtime
(which I already kinda deprecated before). The existing Tegra chipsets
that still used it are switched to instead define it in memlayout in a
minimally invasive change. This might not be the best way to design this
overall (I think we should probably just throw the tables into SRAM like
on all other platforms), but I don't have a Tegra system to test so I'd
rather keep this change low impact and leave the major redesign for
later.
Also inlined some single-use one-liner functions in mmu.c that I felt
confused things more than they cleared up, and fixed an (apparently
harmless?) issue with forgetting to mask out the XN page attribute bit
when casting a table descriptor to a pointer.

Among its other restrictions (which are noted in a comment above the
function prototype and stay in place), our makeshift fine-grained page
table support for ARM32 has the undocumented feature that it relies on
a global bookkeeping variable, causing all sorts of fun surprises when
you try to use it from multiple stages during the same boot. This patch
redesigns the bookkeeping to stay completely inline in the (persistent)
TTB which should resolve the issue. (This had not been a problem on any
of our platforms for now... I just noticed this because I was trying to
solve the same issue on ARM64.)
