drm/i915: Enable display WA#1183 from its correct spot
commit ac315c621f01d4b8a53dec317c7ae322fd26ff38 upstream.
The DMC FW specific part of display WA#1183 is supposed to be enabled
whenever enabling DC5 or DC6, so move it to the DC6 enable function
from the DC6 disable function.
I noticed this after Daniel's patch to remove the unused
skl_disable_dc6() function.
Fixes: 53421c2fe99c ("drm/i915: Apply Display WA #1183 on skl, kbl, and cfl")
