drm/i915: Skip register reads in i915_get_crtc_scanoutpos()
We have all the information we need in the mode structure, so going and
reading it from the hardware is pointless, and slower.
We never populated ->get_vblank_timestamp() in the UMS case, and as that
is the only way we'd ever call ->get_scanout_position(), we can
completely ignore UMS in i915_get_crtc_scanoutpos().
Also reorganize intel_irq_init() a bit to clarify the KMS vs. UMS
situation.
v2: Drop UMS code
