DL register is not set to drive number when detecting EDD for drive,
so detection may fail.

As per commit f775e740a3a817a4ff5ba26bea99dbfd735456b3, inreg parameters
of intcall() shall be zeroified.
Having unclean inreg could trigger bad behaviors on some hosts.
This patch is about adding memset() calls prior any intcall() :
- some intcall didn't had any memset at all
- some successive intcall() calls didn't memset inreg in between calls

We've currently got both the BIOS and EFI versions of struct
disk_private in core/include/disk.h, which isn't ideal because this
file shouldn't need to know about the inner-workings of the firmware's
private disk info.
Move the implementation of 'struct disk_private' into more suitable
locations and use a void * for the 'private' member of struct disk.
This change allows us to once and for all delete the gnu-efi header
files from core/include/core.h and the gnu-efi include paths from
mk/lib.mk.

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.
