drm/i915: Disable sprite gamma on ivb-bdw 



We don't currently have any use for the sprite gamma on ivb-bdw.
Let's disable it. We already do that on skl+.

On pre-ivb there is no way to disable the sprite gamma, and it
only affects YCbCr pixel formats, whereas on ivb+ it also
affects RGB formats.
