The symbol is an orphan, get rid of it.

We don't support the ISA DMA API, so this is only ever misused. The
dma-sh case inadvertently broke the dreamcast case by testing the wrong
variable for the total number of channels, so this fixes that up too.

This supported all DMA channels, and it was tested in SH7722,
SH7780, SH7785 and SH7763.
This can not use with SH DMA API.

Update intc tables and platform data to use one linux irq
per maskable interrupt source instead of keeping the one-to-one
mapping between vectors and linux irqs.
This fixes potential irq masking issues for sh7760 hardware
blocks such as DMAC/TMU2/REF.

This accidentally regressed when the multi-IRQ changes went in,
switching SH7091 from 4 to 6 channels. Add SH7091 back in to the
4-channel dependency list.

With arch/sh/drivers/dma/ always being built, the Dreamcast DMA engines
are being unconditionally built in, regardless of whether the DMA API is
enabled or not. This is a regression from previous behaviour, but there
is not much advantage in building them all in unconditionally regardless.
Add a new config option to make it optional, and update the only user of
it to reflect that.

When SuperH CPU has IRQ multi of DMAC, SH_DMA_IRQ_MULTI becomes enable.
The following CPU's are Multi IRQ of DMAC now.
- SH775X and SH7091
- SH776X
- SH7780
- SH7785
If SH_DMA_IRQ_MULTI becomes enable, dma-sh api driver is optimized
for Multi IRQ.

This adds DMA support for newer SH-4A CPUs, particularly SH7763/64/80/85.
This also enables multi IRQ support for platforms that have multiple
vectors bound to the same IRQ source.

Currently this has a prompt to allow users to change it. There's
no reason to do this, and it has caused breakage and confusion
in the past, so remove it entirely.
We'll get rid of this when the whole driver is tidied for
the driver model.

There's no point in keeping these around, they've been broken
for some time, and the dmaenging/async_tx framework provides a
far more reasonable interface.

The DMABRG is a special DMA unit within the SH7760 which does data
transfers from main memory to Audio units and USB shared memory.
It has 3 IRQ lines which generate 10 events, which have to be masked
unmasked and acked in a single 32bit register. It works independently
from the tradition SH DMAC, but blocks usage of DMAC channel 0.
This patch adds 2 functions to associate callbacks with DMABRG events
and initialization.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
