pvr2fb: Consolidated cleanup of pvr2fb.c
- better handling of the pvr2 registers based on more up to date
information.
Testing shows that it seems to work pretty well at 16bpp, 24bpp and 32bpp -
including proper rendering of the boot logo at all levels (previously this
was
a bit broken even at 16bpp) and giving white against black text. Really
detailed testing (eg with X11) requires support for the maple bus - which
isn't (currently - next project assuming this is okay) available, but I have
no reason to think this is broken.
