I may be wrong about this, but there doesn't seem to be any important hardware connected to this bus.
All the hardware components I know of seem to work fine without dw_dmac loaded.
I don't remember where I read this, but if there was hardware connected to the HSUART (Bluetooth, GPS, things like that), blacklisting dw_dmac will make those devices run at PIO speeds instead of DMA.
To my knowledge, there are no other side effects. See bug #1319149 for more information.
