drm/i915: Prevent using uninitialized MMIO funcs
For upcoming patches which will have GEN specific MMIO functions, we'll
need to initialize the uncore data structure earlier than we do today.
If we do not do this, the following will be problematic:
intel_uncore_sanitize
intel_disable_gt_powersave
gen6_disable_rps
I915_WRITE(GEN6_RC_CONTROL, 0); <--- MMIO
intel_uncore_init // initializes MMIO
By initializing the function pointers first, we should be safe.
