This fixes an issue discovered in A/UX whereby attempts to read the colour LUT from the macfb device returned zero (black) for all colours. The problem was that the DAFB_RESET register is actually used to set the current colour palette array index: fixing that and allowing larger access sizes allows the test case to work.
This series implements these changes, along with renaming the DAFB_RESET register to DAFB_LUT_INDEX which better describes its purpose.
