Add the required pieces to support the EFI loader on x86.
Since U-Boot only builds for 32-bit on x86, only a 32-bit EFI application is supported. If a 64-bit kernel must be booted, U-Boot supports this directly using FIT (see doc/uImage.FIT/kernel.its). U-Boot can act as a payload for both 32-bit and 64-bit EFI.
