Mika Kuoppala f9b3927afb drm/i915: Do uncore early sanitize after domain init
intel_uncore_early_sanitize() will reset the forcewake registers. When
forcewake domains were introduced, the domain init was done after the
sanitization of the forcewake registers. And as the resetting of
registers use the domain accessors, we tried to reset the forcewake
registers with unitialized forcewake domains and failed.

Fix this by sanitizing after all the domains have been initialized. Do
per domain clearing of forcewake register on domain init so that
IVB can do early access to ECOBUS do determine the final configuration.

This regression was introduced in
