Make the PS3 ps3av driver a loadable module.
- Replace static data with kmalloc()'ed.
o Allocate struct ps3av dynamically, as it contains data used as vuart
receive/transmit buffers
o Move static recv_buf from ps3av_do_pkt() to struct ps3av
- Move ps3av_vuart_{read,write}() from drivers/ps3/ps3av_cmd.c to
drivers/ps3/ps3av.c and make them static as they're used in that file only.
- Make device a PS3 system-bus device.
- Update copyright formatting.
- Make two new routines ps3av_register_flip_ctl() and ps3av_flip_ctl() to
support late binding of the frame buffer flip control routine.

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).
