x86: EFI runtime service support
This patch adds basic runtime services support for EFI x86_64 system. The
main file of the patch is the addition of efi_64.c for x86_64. This file is
modeled after the EFI IA32 avatar. EFI runtime services initialization are
implemented in efi_64.c. Some x86_64 specifics are worth noting here. On
x86_64, parameters passed to EFI firmware services need to follow the EFI
calling convention. For this purpose, a set of functions named efi_call<x>
(<x> is the number of parameters) are implemented. EFI function calls are
wrapped before calling the firmware service. The duplicated code between
efi_32.c and efi_64.c is placed in efi.c to remove them from efi_32.c.
