To prepare for completely separating the VGA console screen_info from the one used in EFI/sysfb, rename the vgacon instances and make them local as much as possible. ia64 and arm both have confurations with vgacon and efi, but the contents never overlaps because ia64 has no EFI framebuffer, and arm only has vga console on legacy platforms without EFI. 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 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.
