Kernel: Move PC BIOS-related code to the x86_64 architecture directory

Browse source 
All code that is related to PC BIOS should not be in the Kernel/Firmware
directory as this directory is for abstracted and platform-agnostic code
like ACPI (and device tree parsing in the future).

This fixes a problem with the aarch64 architecure, as these machines
don't have any PC-BIOS in them so actually trying to access these memory
locations (EBDA, BIOS ROM) does not make any sense, as they're specific
to x86 machines only.
