Fix the black and white stripes issue with WUXGA monitor via HDMI.
It seems that when we use a VESA resolution from boot up, the AV settings
driver could not be initialized correctly. In that case we need a dummy
packet before VESA setting.
[Geert] Refactored to reduce code duplication.

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.

PS3_SM_EVENT_POWER_PRESSED.
- Make the PS3 sys-manager driver a loadable module.
- Add new file sys-manager-core.c.
- Add new struct ps3_sys_manager_ops for dynamic binding.
- Put data sent to device on stack.
- Add support for PS3_SM_SERVICE_ID_REQUEST_ERROR.

PS3 vuart updates to reflect the new PS3 unified device support.
- Move vuart devices to the PS3 system bus.
- Replace use of ps3_vuart_port_device with ps3_system_bus_device.

- Remove redundant spinlock ps3_vuart_work.lock.
- No longer free ps3_vuart_port_device.priv on shutdown.
- Cleanup Kconfig defs.
- Export symbols needed for modular port drivers.
- Arrange to use port numbers found in repository.
- Fix bugs in ps3_vuart_read_async() and polled reading
- Cleanup handling of shared interrupt with ps3_vuart_bus_interrupt_get()
and ps3_vuart_bus_interrupt_put()
- Add more comments to vuart.c.

ps3av:
- Move the definition of struct ps3av to ps3av.c, as it's locally used only.
- Kill ps3av.sem, use the existing ps3av.mutex instead.
- Make the 512-byte buffer in ps3av_do_pkt() static to reduce stack usage.
Its use is protected by a semaphore anyway.

Commit 404d5b185b changed the definition
of dev_dbg in the !DEBUG case from being a #define to being a static
inline. There was code in drivers/ps3/vuart.c to do exactly that,
which fails to compile now. This fixes it by removing the redefinition,
as the redefinition is now superfluous.

Add missing checks to PS3 specific drivers ps3av and sys-manager to verify that
we are actually running on a PS3 (pointed out by Arnd).
Correct existing checks in other subsystems/drivers to return -ENODEV instead
of zero.

Add PS3 system manager support and the ppc_md routines restart() and
power_off().
The system manager provides an event notification mechanism for reporting
events like thermal alert and button presses. It also provides support to
control system shutdown and startup.
