If the F: description is to be trusted, the two xen/arch/x86/hvm/
lines were fully redundant with the earlier wildcard ones. Arch header
files, otoh, were no longer covered by anything as of the move from
include/asm-*/ to arch/*/include/asm/. Finally also generalize (by
folding) the x86- and Arm-specific mem_access.c entries.

Triggered by me looking at the entry in the context of Oleksii's RISC-V
preparatory patch.

We could go further, to simply
F:	xen/*/mem_access.[ch]
F:	xen/*/monitor.[ch]
F:	xen/*/vm_event.[ch]
Thoughts anyone?
