MIPS: Alchemy: change dbdma to accept physical memory addresses

Browse Source 
DMA can only be done from physical addresses; move the "virt_to_phys"
source/destination buffer address translation from the dbdma queueing
functions (since the hardware can only DMA to/from physical addresses)
to their respective users.
