Subject: 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.
