hwaccess: fix build on non-x86 targets

The changes to hwaccess in commit 49d758698a0dd166679c48b1a2785e50e9b0cc83
cause build failure on non-x86 systems because the hwaccess_x86_*
headers are included in some files that are built for all platforms
(particularly those in the internal programmer) and those headers in
turn include <sys/io.h> which only exists on x86.

This change avoids including those headers on non-x86 platforms so
the internal programmer can be built without errors.

The comment on the stub implementation of rget_io_perms() is also
modified to remove references to non-x86 platforms, since that file is
only built on x86 now.

BUG=None
TEST=meson build succeeds for both x86 and ARM targets
