x86: fix DMI on EFI
Impact: reactivate DMI quirks on EFI hardware DMI tables are loaded by EFI, so the dmi calls must happen after efi_init() and not before. Currently Apple hardware uses DMI to determine the framebuffer mappings for efifb. Without DMI working you also have no video on MacBook Pro. This patch resolves the DMI issue for EFI hardware (DMI is now properly detected at boot), and additionally efifb now loads on Apple hardware (i.e. video works).
