Tijl Coosemans 2d97bd0639 linuxkpi: Make arch_io_*_memtype_wc amd64-only
Linux only implements these functions on x86.  They return 0 on other
architectures.  The FreeBSD implementation calls PHYS_TO_DMAP but this
panics on i386 because it does not have a direct map so return 0 on i386
as well for now.  These functions are only used by graphics/drm-*-kmod
to mark the VRAM aperture write-combining but this is also accomplished
by a call to vm_phys_fictitious_reg_range so this change is sufficient
to fix drm-*-kmod on i386 for FreeBSD 14.1.
