    drm/i915: Create a more generic pm handler for hsw+

    HSW has some special requirements for the VEBOX. Splitting out the
    interrupt handler will make the code a bit nicer and less error prone
    when we begin to handle those.

    The slight functional change in this patch (queueing work while holding
    the spinlock) is intentional as it makes a subsequent patch a bit nicer.
    The change should also only effect HSW platforms.
