x86, efi: Don't use (U)EFI time services on 32 bit

Browse source 
commit 04bf9ba720 upstream.

UEFI time services are often broken once we're in virtual mode. We were
already refusing to use them on 64-bit systems, but it turns out that
they're also broken on some 32-bit firmware, including the Dell Venue.
Disable them for now, we can revisit once we have the 1:1 mappings code
incorporated.
