CONFIG_EFI_PGT_DUMP=y, as the name suggests, dumps EFI page tables to the kernel log during kernel boot. This feature is very useful while debugging page faults/null pointer dereferences to EFI related addresses. Presently, this feature is limited only to x86_64, so let's extend it to other EFI configurations like kexec kernel, efi=old_map and to x86_32 as well. This doesn't effect normal boot path because this config option should be used only for debug purposes.
