Hi folks,

Big-endian support on arm64 (CONFIG_CPU_BIG_ENDIAN) has depended on
BROKEN since 1cf89b6bf660 ("arm64: Kconfig: Make CPU_BIG_ENDIAN depend
on BROKEN") and has already seen some clean-up patches removing some of
the unused support code (e.g. 5276ea17a23c ("lib/crc: arm64: Assume a
little-endian kernel")).

Finish the job, and remove the remaining big-endian support code from
arm64. Note that the SETEND emulation for 32-bit tasks remains and so
some of the mixed-endian EL0 helpers are retained.

I've broken this down into fairly coarse chunks, as it seemed a lot
easier to manage than one giant patch (even with the Kconfig being
effectively disabled already) and not all of it is just mindless
deletion. Despite that, I'm anticipating the whole thing going via the
arm64 tree.

FWIW:
