MIPS: Alchemy: fix dbdma2
[ Upstream commit 2d645604f69f3a772d58ead702f9a8e84ab2b342 ]
Various fixes for the Au1200/Au1550/Au1300 DBDMA2 code:
- skip cache invalidation if chip has working coherency circuitry.
- invalidate KSEG0-portion of the (physical) data address.
- force the dma channel doorbell write out to bus immediately with
a sync.
