[PATCH 00/05] SH-Mobile ARM dmaengine support V1

SH-Mobile ARM dmaengine support V1

[PATCH 01/05] dmaengine: shdma: Remove sh_dmae_slave_chan_id enum
[PATCH 02/05] dmaengine: shdma: Common SH_DMA_SLAVE_NUMBER
[PATCH 03/05] serial: sh-sci: Use sg_dma_len() and sg_dma_address()
[PATCH 04/05] dmaengine: shdma: Introduce include/linux/sh_dma.h
[PATCH 05/05] dmaengine: shdma: Enable on SH-Mobile ARM

These patches add support for the shdma dmaengine driver on
SH-Mobile ARM. Since some of the data structures are used by
various drivers these patches modify both SH architecture code,
dmaengine, sh-sci and the recently added siu sound driver.

Not sure how to merge this smoothly, but I tried to layer the
changes so they can be added one at a time without breaking
anything.

Compiles fine on sh7377 G4EVM (ARM) and sh7722 Migo-R (SH).

Ok, I've taken these in to the sh/dmaengine topic branch, particularly
since there's on-going work with the serial DMA stuff. I'll pull this in
to a topic branch in the genesis tree and apply the 5th one on top of
a bit later once I've dealt with the rest of the backlog.
