x86/pkeys: Move read_pkru() and write_pkru()
write_pkru() was originally used just to write to the PKRU register. It
was mercifully short and sweet and was not out of place in pgtable.h with
some other pkey-related code.
But, later work included a requirement to also modify the task XSAVE
buffer when updating the register. This really is more related to the
XSAVE architecture than to paging.
Move the read/write_pkru() to asm/pkru.h. pgtable.h won't miss them.
