ahci: Fix FLUSH command

AHCI couldn't cope with asynchronous commands that aren't doing DMA, it
simply wouldn't complete them. Due to the bug fixed in commit f68ec837,
FLUSH commands would seem to have completed immediately even if they
were still running on the host. After the commit, they would simply hang...

PPC: dbdma: macio: Add DMA callback

We need to know when the IDE core starts a DMA transfer. Add a notifier
function so we have the chance to start transmitting data.

PPC: dbdma: Wait for DMA until we have data

We should only start processing DMA requests when we have data to process.
Hold off working through the DMA shuffling until the IDE core told us that
it's ready.

This is required because the guest can program the DMA engine or the IDE...

PPC: dbdma: Support unaligned DMA access

The DBDMA engine really just reads bytes from a producing device (IDE
in our case) and shoves these bytes into memory. It doesn't care whether
any alignment takes place or not.

Our code today however assumes that block accesses always happen on...

PPC: dbdma: Support more multi-issue DMA requests

A DMA request can happen for data that hasn't been completely been
provided by the IDE core yet. For example

- DBDMA request for 0x1000 bytes
  - IDE request for 1 sector
  - DBDMA wants to read 0x1000 bytes (8 sectors) from bdrv...

PPC: Mac: Add debug prints in macio and dbdma code

The macio code is basically undebuggable as it stands today, with no
debug prints anywhere whatsoever. DBDMA was better, but I needed a
few more to create reasonable logs that tell me where breakage is.
