Julius Werner 02a2fe7907 Merge coreboot and libpayload <endian.h> into commonlib
We've accumulated a number of endianness-handling and related macros
that are duplicated between coreboot and libpayload. This patch reduces
duplication by merging them into a commonlib header. This has the added
side-benefit of bringing the coreboot implementation of beXXenc/dec()
functions to libpayload, which lead to better code generation by
avoiding https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92716.

Keep the htobell()-style functions in libpayload only since they're not
needed in coreboot and not preferred. Keep the cpu_to_beXX()-style
functions in coreboot only -- maybe we should deprecate those
eventually.

This patch is explicitly copying and relicensing some of the code I
originally added as GPLv2 in commit e8e92d60c4 ("endian.h: Add
be32dec/be32enc family of functions") to BSD-3.
