This patch adds config ARCH_RISCV_RV64 to support build of riscv64
payloads. New files under arch/riscv contain:
- Basic ldscript and payload entry point.
- Functions for riscv64 io and cache operations.
- Default timer code based on mtime delegation.
- Default cb_header_ptr passing with device tree to payload.

I got 'nm' usage error when i built coreinfo payload.
nm: unrecognized option '--no-weak'
it seems that this is occurred by using nm for host, not for coreboot.
So, I replace nm with $(NM)

Weak symbols don't work as expected when you try to override them from
within the same static library. Static libraries are just archives of
individual objects, and when the linker tries to resolve a symbol
against it it simply uses the implementation from the first object that
has one, weak or not. It does not search through all remaining objects
to see if there's also a strong implementation.
We've had multiple cases in libpayload where builds were incorrectly
using the default implementation rather than an optimized arch-specific
implementation for years due to this issue. To prevent it from
recurring, this patch adds some postprocessing script to the Makefile
that checks for this situation and makes the build fail if it creeps in
again.

- Added `$(obj)/libpayload-config.h` as a dependency for the `lib`
target.
- This ensures the config header is up-to-date before building the
library.
TEST=Able to build google/rex.

This patch introduces x86_64 (64-bit) support to the payload, building
upon the existing x86 (32-bit) architecture. Files necessary for 64-bit
compilation are now guarded by the `CONFIG_LP_ARCH_X86_64` Kconfig
option.

payload with this patch.

Integrate head.S directly into libc and remove all instances of head.o.
* Drop 'separate class' entry for head.S.
* Drop special treament for head.o inside lpgcc.
* Change the .text in `x86/head.S` to `.section .text._entry`.
* Drop arch/mock/head.c, initially added as a dummy file.

CB:77968 made some non-BSD commonlib files part of libpayload when
CONFIG_LP_GPL is set. This patch exports those headers to the payload
(again only when CONFIG_LP_GPL is set) so that payloads can also call
the functions in them directly.
Also make those includes available to tests so that their functions can
be tested. There's no menuconfig for unit tests, so they are included
unconditionally, but this should be fine since the tests are standalone
and won't have to link with any proprietary third-party code.

The .inc suffix is confusing to various tools as it's not specific to
Makefiles. This means that editors don't recognize the files, and don't
open them with highlighting and any other specific editor functionality.
This issue is also seen in the release notes generation script where
Makefiles get renamed before running cloc.
