Renaming these is required before the EFI screen_info can be moved into drivers/firmware. The ia64 vga console is actually registered in two places from setup_arch(), but one of them is wrong, so drop the one in pcdp.c and the fix the one in setup.c to use the correct conditional. x86 has to keep them together, as the boot protocol is used to switch between VGA text console and framebuffer through the screen_info data.
