hwaccess: fix build on non-x86 targets
The changes to hwaccess in https://review.coreboot.org/c/flashrom/+/60110
cause build failure on non-x86 systems because:
* a new include file pulls in <sys/io.h> which only exists on x86 but
the header may be used on other platforms
* the new rget_io_perms function only works on x86
This change makes sys/io.h and rget_io_perms implementation only be
included when building for x86 targets, which fixes the build on ARM.
BUG=None
TEST=meson build succeeds for both x86 and ARM targets
