[PATCH v3 08/10] drm/i915/xehp: Make IRQ reset and postinstall multi-tile aware

[Matt Roper]

From: Paulo Zanoni <paulo.r.zanoni at intel.com>

Loop through all the tiles when initializing and resetting interrupts.

v2:
 - Access tile0 registers through dev_priv->uncore rather than
   dev_priv->gt.uncore for clarity.
