ide: honor ncq for atapi

ATAPI also can do ncq, so let's expose the capability.

This patch makes CD-ROM support work on Windows 7 for me.

ide: Register vm change state handler once only

We register the vm change state handler in a PCI BAR map() function.
This function can be called multiple times throughout the lifetime of a
PCI IDE device. This results in duplicate vm change state handlers...

ide: add ncq identify data for ahci sata drives

I modified ide_identify() to include the zero-based queue length
value in word 75, and set bit 8 in word 76 to signal NCQ support
in the identify data for AHCI SATA drives.

ahci: add ahci emulation

This patch adds an emulation layer for an ICH-9 AHCI controller. For now
this controller does not do IDE legacy emulation. It is a pure AHCI controller.

ide: Split out BMDMA code from ATA core

The ATA core is currently heavily intertwined with BMDMA code. Let's loosen
that a bit, so we can happily replace the DMA backend with different
implementations.

ide: move transfer_start after variable modification

We hook into transfer_start and immediately call the end function
for ahci. This means that everything needs to be in place for the
end function when we start the transfer, so let's move the function
down to where all state is in place....

ide: split ide command interpretation off

The ATA command interpretation code can be used for PATA and SATA
interfaces alike. So let's split it out into a separate function.

ide: fix whitespace gap in ide_exec_cmd

Now that we have the function split out, we have to reindent it.
In order to increase the readability of the actual functional change,
this is split out.

Add bootindex parameter to net/block/fd device

If bootindex is specified on command line a string that describes device
in firmware readable way is added into sorted list. Later this list will
be passed into firmware to control boot order.
