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.
