We were truncating the image offset within the target image to 16 bits
which again meant that we were potentially overwriting random memory
in the lower 16 bits of the image.
This patch casts the offset to a more reasonable 32bits.
With this applied, I can successfully see Shell.efi assert because it
can't find a protocol it expects to be available.

When switching between EFI context and U-Boot context we need to swap
the register that "gd" resides in.
Some functions slipped through here, with efi_allocate_pool / efi_free_pool
not doing the switch correctly and efi_return_handle switching too often.
Fix them all up to make sure we always have consistent register state.

EFI uses the PE binary format for its application images. Add support to EFI PE
binaries as well as all necessary bits for the "EFI image loader" interfaces.
