[Intel-gfx] [PATCH 01/11] drm/i915: Export low level PM IRQ functions to control from GuC functions

[Sagar Arun Kamble]

In order to separate GuC IRQ handling functions from i915_irq.c we need
to export the low level pm irq handlers. Export pm_iir, reset_pm_iir and
enable/disable_pm_irq functions.
