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.
