elf64: Add LE64 ABIv1/2 support for loading images to given address
c2358afb40d4 ("Add support for 64bit LE ABI v1 and v2 support") added
little endian ELF support for one of two ELF loading helpers, this fixes
oversight. With this changes, 'boot disk:2,boot\zImage' is able to handle
little-endian zimages.
