Add OHCI shutdown methods to cleanly shutdown the OHCI controller on

As the DMA engine API allows DMA channels to be reconfigured on the
fly, we can now support switching the DMA channel configuration to
support SIR transmit DMA without needing to claim an additional
physical DMA channel - thereby using up half the DMA channels just
for one driver.

Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Add support for the SA-11x0 DMA driver, which replaces the private
API version in arch/arm/mach-sa1100/dma.c.

We model this as a set of virtual DMA channels, one for each request
signal, and assign the virtual DMA channel to a physical DMA channel
when there is work to be done.  This allows DMA users to claim their
channels, and hold them while not in use, without affecting the
availability of the physical channels.

Another advantage over this approach, compared to the private version,
is that a channel can be reconfigured on the fly without having to
release and re-request it - which for the IrDA driver, allows us to
use DMA for SIR mode transmit without eating up three physical
channels.  As IrDA is half-duplex, we actually only need one physical
channel, and this architecture allows us to achieve that.

The sa11x0-ir device is not the device which is doing the DMA, the
DMA is being performed by a separate DMA engine.  Split the struct
device associated with each DMA channel from the main struct device,
but for the time being initialize it from the main struct device.

This is another preparatory step to converting this driver to use the
DMA engine API.

The SIR transmit buffer was being allocated as 4000 bytes.  IrDA now
has constants for the buffer sizes, and defines the maximum wrapped
SIR packet to be 4269 bytes as indicated by IRDA_SIR_MAX_FRAME.  Use
this definition to allocate the transmit buffer instead.

Ensure that we unmap and free a pending transmit skb when the interface
