[Intel-gfx] [PATCH 10/24] drm/i915: Leave interrupts enabled while disabling crtcs during suspend

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

The new watermaek update mechanism requires interrupts to work
correctly. Because of this we need interrupts while disabling crtcs
during suspend. So move the irq disable to happen a bit later.
