firmware, diskio: Create struct disk_private

We need a way of passing firmware-specific information to the disk I/O
subsystem. Split the BIOS code into diskio_bios.c so that we don't
include any disk BIOS symbols in the EFI executable. This way, the
code in core/fs/diskio.c is firmware independent.
