The device info offset arrays for unevenly spaced register offsets is
great for widely used registers. However, the palette registers are only
used in one function, i9xx_load_luts_internal(), and only for GMCH
platforms, wasting device info. Replace palette_offsets with _PICK() in
palette register definition.
While the use of _PICK() does not check for pipe C existence, neither
does the current offset array usage, and leads to bogus address when
pipe C is passed to PALETTE() on non-CHV. Using _PICK() at least leads
to a sensible register offset, just non-existing on non-CHV. Either way,
this shouldn't happen anyway.
Remove unused old palette macros while at it.
Bloat-o-meter results below for completeness.
