Subject: drm/i915: save/restore interrupt state

On resume, if the interrupt state isn't restored correctly, we may end
up with a flood of unexpected or ill-timed interrupts, which could cause
the kernel to disable the interrupt or vblank events to happen at the
wrong time.  So save/restore them properly.

Subject: drm/i915: restore pipeconf regs unconditionally

On many chipsets, the checks for DPLL enable or VGA mode will prevent the pipeconf regs from being restored, which could result in a blank display or X failing to come back after resume.  So restore them unconditionally along with actually restoring pipe B's palette correctly.

Subject: drm/i915: Fix hibernate save/restore of VGA attribute regs

In hibernate, we may end up calling the VGA save regs function twice, so we need to make sure it's idempotent.  That means leaving ARX in index mode after the first save operation.  Fixes hibernate on 965.
