efi: Greatly simplify the EFI Scan Code handling
By adding the EFI Scan Codes to 'keycodes' in get_key.c, prefixed with the escape sequence '\0' to avoid clashes with ASCII characters, we can have all the input key decoding done in one place, allowing us to delete efi/keymap.h. Luckily there are no conflicts with the combined BIOS codes already present in 'keycodes', though if we were to add the EFI scan code for the pause key (0x48) that would conflict with the existing BIOS code for KEY_UP. Still, it shouldn't be necessary to add any more scan codes because it doesn't make sense for things like the mute key to be handled by Syslinux. Signed-off-by: Matt Fleming <matt.fleming@intel.com>
