Ben Widawsky 7083e05072 drm/i915: Fix RC6VIDS encode/decode 
The RC6 VIDS has a linear ramp starting at 250mv, which means any values
below 250 are invalid. The old buggy macros tried to adjust for this to
be more flexible, but there is no need. As Dan pointed out the ENCODE
only ever has one value. The only invalid value for decode is an input
of 0 which means something is really wonky, and the cases where DECODE
are used either don't matter (debug values), or would be implicitly
correct (the check for less than 450).

This patch makes simpler, easier to read macros which are actually
correct. Maybe this patch can actually fix some bugs now.

Thanks to Dan for catching this. /me hides
