[PATCH 4/4] drm/intel: Push get_scanout_position() timestamping into kms driver.

Move the ktime_get() clock readouts and potential preempt_disable() calls from drm core into kms driver to make it compatible with the api changes in the drm core. The intel-kms driver needs to take the uncore.lock inside i915_get_crtc_scanoutpos() and intel_pipe_in_vblank(). This is incompatible
