This is a set of changes that converts the PMAZ-A support to the driver model.
The use of the driver model required switching to the hotplug SCSI
initialization model, which in turn required a change to the core NCR53C9x
driver. I decided not to break all the frontend drivers and introduced an
additional parameter for esp_allocate() to select between the old and the new
model. I hope this is OK, but I would be fine with converting NCR53C9x to the
new model unconditionally as long as I do not have to fix all the other
frontends (OK, perhaps I could do some of them ;-) ).

well. Plus support for MMIO in addition to PIO operation as TURBOchannel

Nowadays MTD supports an MTD_OOB_AUTO option which allows users
to access free bytes in NAND's OOB as a contiguous buffer, although
it may be highly discontinuous.
This patch teaches JFFS2 to use this nice feature instead of the
old MTD_OOB_PLACE option. This for example caused problems with
OneNAND. Now JFFS2 does not care how are the free bytes situated.
This may change position of the clean marker on some flashes,
but this is not a problem. JFFS2 will just re-erase the empty
eraseblocks and write the new (correct) clean marker.

- It's not OK to change the flow handler as part of set_irq_type(),
among other issues that violates spinlock rules. Instead, we can
call the relevant handler when we demux the external interrupts.
- The external irq demux has no need to grab the spinlock. And in
fact grabbing it that way was wrong, since that code might be
pre-empted by an irq at a different priority level, and that code
might then have tried to grab that spinlock...

This fixes the problem of getting extra bytes inserted at the
beginning of a recording when using the Apple i2s interface and DBDMA
controller. It turns out that we can't just abort the DMA; we have to
let it stop at the end of a command, and then wait for the S7 bit to
be set before turning off the DBDMA controller. Doing that for
playback doesn't seem to be necessary, but doesn't hurt either.
We use the technique used by the Darwin driver: make each transfer
command branch to a stop command if the S0 status bit is set. Thus we
can ask the DMA controller to stop at the end of the current command
by setting S0.
The interrupt routine now looks at and clears the status word of the
DBDMA command ring. This is necessary so it can know when the DBDMA
controller has seen that S0 is set, and so when it should look for the
DBDMA controller being stopped and S7 being set. This also ended up
simplifying the calculation in i2sbus_pcm_pointer.
Tested on a 15 inch albook.
