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.

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 404d5b185b4eb56d6fa2f7bd27833f8df1c38ce4 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.

Fix two minor bugs in the PS3 system bus mmio region code. First, on error or
when freeing a region, retain the bus_addr and len fields to allow subsequent
calls to create the region. Second, correct the region address argument to the
lv1_unmap_device_mmio_region() call.
Fixes modprobe/rmmod of some drivers.

A few code paths need to check whether or not they are running
on the PS3's LV1 hypervisor before making hcalls. This introduces
a new firmware feature bit for this, FW_FEATURE_PS3_LV1.
Now when both PS3 and IBM_CELL_BLADE are enabled, but not PSERIES,
FW_FEATURE_PS3_LV1 and FW_FEATURE_LPAR get enabled at compile time,
which is a bug. The same problem can also happen for (PPC_ISERIES &&
!PPC_PSERIES && PPC_SOMETHING_ELSE). In order to solve this, I
introduce a new CONFIG_PPC_NATIVE option that is set when at least
one platform is selected that can run without a hypervisor and then
turns the firmware feature check into a run-time option.
The new cell oprofile support that was recently merged does not
work on hypervisor based platforms like the PS3, therefore make
it depend on PPC_CELL_NATIVE instead of PPC_CELL. This may change
if we get oprofile support for PS3.
