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).
