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.
