The i915 driver is now using atomic properties and atomic commit
to handle the legacy set gamma IOCTL. However, if the driver is
configured without atomic (nuclear_pageflip = false), it won't
update the legacy properties for degamma_lut, gamma_lut and ctm
leaving them out of sync with the atomic version of the properties.
Until the driver is full atomic, make sure we update the non-atomic
version of the properties.
v2: Update the comment with a FIXME. (Daniel)
v3: Update arguments of the gamma_set vfunc (Lionel)
v4: Fixed vfunc prototype (Lionel)
