x86, efi: Abstract x86 efi_early calls
The ARM EFI boot stub doesn't need to care about the efi_early infrastructure that x86 requires in order to do mixed mode thunking. So wrap everything up in an efi_call_early() macro. This allows x86 to do the necessary indirection jumps to call whatever firmware interface is necessary (native or mixed mode), but also allows the ARM folks to mask the fact that they don't support relocation in the boot stub and need to pass 'sys_table_arg' to every function.
