arm64: pass endianness info to sparse
ARM64 depends on the macro __AARCH64EB__ being defined or not
to correctly select or define endian-specific macros, structures
or pieces of code.
This macro is predefined by the compiler but sparse knows nothing
about it and thus may pre-process files differently from what
gcc would.
Fix this by passing '-D__AARCH64EL__' or '-D__AARCH64EB__' to
sparse depending of the endianness of the kernel, like defined
by GCC.
Note: In most case it won't change anything since most arm64 use
little-endian (but an allyesconfig would use big-endian!).
