Supporting earlier userspace requires at least command
table to remap the renumbered commands. I did some initial
tests on that, but did not get sgx initialized yet.

I actually ended up writing a new pvr-drv.c file, will
post it shortly. So it should stay separate from whatever
you do with scripts hopefully. I added:

pvr-drv.c
pvr-drv.h

Added that too :)

For supporting multiple different register layouts in
the same driver, we should probably just add:

pvr-sgx530.c
pvr-sgx540.c
pvr-sgx544.c
...

Where the right one gets initialized based on the compatible.
