MIPS: Octeon: Update DMA mapping operations for OCTEON II processors.

Browse Source 
OCTEON II has a new dma to phys mapping method for PCIe.  Define
OCTEON_DMA_BAR_TYPE_PCIE2 to denote this case, and handle it.

OCTEON II also needs a swiotlb if the OHCI USB driver is enabled, so
allocate this too.
