macfb: rename DAFB_RESET to DAFB_LUT_INDEX 

When A/UX uses the MacOS Device Manager Status (GetEntries) call to read the
contents of the CLUT, it is easy to see that the requested index is written to
the DAFB_RESET register. Update the palette_current index with the requested
value, and rename it to DAFB_LUT_INDEX to reflect its true purpose.
