ps3: Replace direct file operations by callback
Currently the FLASH database is updated by the kernel using file operations,
meant for userspace only. While this works for us because copy_{from,to}_user()
on powerpc can handle kernel pointers, this is unportable and a bad example.
Replace the file operations by callbacks, registered by the ps3flash driver.

powerpc/ps3: Use dma_addr_t down through the stack
Push the dma_addr_t type usage all the way down to where the actual
values are manipulated.
Now that u64 is "unsigned long long", this removes warnings like:

mtd/ps3vram: Add ps3vram driver for accessing video RAM as MTD
Add ps3vram driver, which exposes unused video RAM on the PS3 as a MTD
device suitable for storage or swap. Fast data transfer is achieved
using a local cache in system RAM and DMA transfers via the GPU.

powerpc/ps3: Add sub-match id modalias support
commit 059e4938f8b060b10c4352e6c45739473bc73267 ("powerpc/ps3: Add a sub-match
id to ps3_system_bus") forgot to update the module alias support:
- Add the sub-match ids to the module aliases, so udev can distinguish
between different types of sub-devices.
- Rename PS3_MODULE_ALIAS_GRAPHICS to PS3_MODULE_ALIAS_GPU_FB, as ps3fb
binds to the "FB" sub-device.

powerpc/ps3: Replace the flip_ctl logic in ps3av and ps3fb by a mutex
Introduce ps3_gpu_mutex to synchronizes GPU-related operations, like:
- invoking the L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT command using the
lv1_gpu_context_attribute() hypervisor call,
- handling the PS3AV_CID_AVB_PARAM packet in the PS3 A/V Settings driver.

powerpc: Move include files to arch/powerpc/include/asm
from include/asm-powerpc. This is the result of a
mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm
Followed by a few documentation/comment fixups and a couple of places
where <asm-powepc/...> was being used explicitly. Of the latter only
one was outside the arch code and it is a driver only built for powerpc.
