[U-Boot] [PATCH] armv8: Use __aarch64__ rather than CONFIG_ARM64 in some cases

[Tom Rini]

The toolchain sets __aarch64__ for both LE and BE.  In the case of
posix_types.h we cannot reliably use config.h as that will lead to
problems.  In the case of byteorder.h it's clearer to check the EB flag
being set in either case instead.

Hi Tom,

Amended according to Tom's instruction on IRC (actual removal of
config.h include in posix_types.h) then applied on top of the arm64
serie v16.

Amicalement,
