Boot devices which use overriden LCHS values are:
* ata
* ahci
* scsi
* esp
* lsi
* megasas
* mpt
* pvscsi
* virtio
* virtio-blk
We use these values in get_translation() and setup_translation() by
introducing a new translation type: "TRANSLATION_HOST".
We treat this translation as TRANSLATION_NONE in fill_ata_edd(),
although this does not really matter since now the translation between
physical and logical geometry does not exist.

Now that the drive_s struct does not need to be in the f-segment,
rename references to drive_gf in the generic drive code to drive_fl.
This is just variable renames - no code changes.

This patch enables SeaBIOS to boot from NVMe. Finding namespaces and
basic I/O works. Testing has been done in qemu and so far it works with
Grub, syslinux, and the FreeBSD loader. You need a recent Qemu (>=
2.7.0), because older versions have buggy NVMe support.
The NVMe code is currently only enabled on Qemu due to lack of testing
on real hardware.

Support sending scsi style "command data block" commands (cdbcmd)
through the 'struct disk_op_s' command request structure. And change
the blockcmd.c and cdrom.c code to route these commands through the
process_op() code.

Most disk drivers only implement a couple of the available bios
commands. Unify the common fallback handling code into a new function
default_process_op() to reduce boiler-plate code.

This adds basic read/write support for SD cards emulated by QEMU.
This code is not expected to work on real hardware, because the
current controller and card initialization is not robust.

Store the fields necessary to export the "el-torito" spec information
directly in an internal copy of the "el-torito" struct. This
simplifies the interface and obviates the need for an internal home
grown struct with the same info.

Since the XHCI driver needs to jump into 32bit mode anyway, it is
simpler to just run all of the code in 32bit mode.

The "drive" structure is always malloc'ed and therefore always starts
off described as a 32-bit "flat" pointer. Instead of switching
to/from 16bit pointers, make all the code use the 32bit pointer. This
eliminates the confusing 16/32 bit pointer switches.
This patch also removes the "_g" suffixes on local variables in
functions that are always called in 32bit mode.

Testing was done on windows images (win 2008/2012) taken from esx with vmware
tools installed and boot disk configured to use pvscsi.
Also I've used linux (ubuntu 12.04) where pvscsi drivers are installed by
default and booted it using qemu cmd similar to this:
./x86_64-softmmu/qemu-system-x86_64 -snapshot -device pvscsi,id=pvscsi0 \
-device scsi-disk,bus=pvscsi0.0,drive=drive0 \
-drive id=drive0,if=none,file=ubuntu-12.04.qcow2 \
-bios roms/seabios/out/bios.bin

Rename the fields of 'struct chs_s' so that it can be used both to
describe a drive and to describe a particular sector on a drive.
Update floppy.c:lba2chs() to return a 'struct chs_s' instead of
passing the results via pointers.
