[POWERPC] PS3: System-bus rework
Rework the PS3 system bus to unify device support. - DMA region sizes must be a power of two - storage bus DMA updates: - Small fixes for the PS3 DMA core: o fix alignment bug o kill superfluous test o indentation o spelling o export ps3_dma_region_{create,free}() - ps3_dma_region_init(): o Add `addr' and `len' parameters, so you can create a DMA region that does not cover all memory (use `NULL' and `0' to cover all memory). This is needed because there are not sufficient IOMMU resources to have all DMA regions cover all memory. o Uninline - Added remove and shutdown routines to all drivers. - Added loadable module support to all drivers. - Added HV calls for iopte management (needed by sound driver).
