[POWERPC] PS3: Rework AV settings driver
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.
