2f7bb2dfed sh: Fix up MAX_DMA_CHANNELS definition when DMA is disabled. 
MAX_DMA_CHANNELS is tested for the total number of channels in order to
populate an IRQ map. Stub this out completely when no DMA support is
enabled -- as used to be the default behaviour before this was
generalized for use by the dmaengine code.

71b973a42c sh: dma-sh updates for multi IRQ and new SH-4A CPUs. 
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.

f15cbe6f1a sh: migrate to arch/sh/include/ 
This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac.

Most of the moving about was done with Sam's directions at:

with subsequent hacking and fixups entirely my fault.
