drm/i915: kill ivybridge_irq_postinstall
It was very similar to ironlake_irq_postinstall, so IMHO merging both
functions results in a code that is easier to maintain.
With this change, all the irq handler vfuncs between ironlake and
ivybridge are now unified.
v2: Add "(" and ")" to make at least one vim user much happier (Chris)
