Is the "Pre-ICL" comment here a copy/paste error?  The other registers
marked that way say "This field is deprecated" in the bspec, but that
isn't the case for the input CSC.

I don't think we usually add the third address to i915_reg.h when
planes/pipes are equally spaced since our macros can calculate all the
subsequent offsets automatically.  Same also applied to other regs
farther down.

Since these are really just the next dword of the same logical register
as above, maybe it would be simpler to just define these (and the other
dwords of PLANE_INPUT_CSC_COEFF below) as _RY_GY + offset?
