drm/i915: take a reference to uncore in the engine and use it
A few advantages:
- Prepares us for the planned split of display uncore from GT uncore
- Improves our engine-centric view of the world in the engine code
and allows us to avoid jumping back to dev_priv.
- Allows us to wrap accesses to engine register in nice macros that
automatically pick the right mmio base.
