[PATCH] x86: fix EFI memory map parsing
The memory descriptors that comprise the EFI memory map are not fixed in stone such that the size could change in the future. This uses the memory descriptor size obtained from EFI to iterate over the memory map entries during boot. This enables the removal of an x86 specific pad (and ifdef) in the EFI header. I also couldn't stomach the broken up nature of the function to put EFI runtime calls into virtual mode any longer so I fixed that up a bit as well. For reference, this patch only impacts x86.
