[PATCH] drm/i915: Make IRQ reset and postinstall multi-gt aware

[Andi Shyti]

In multi-gt systems IRQs need to be reset and enabled per GT.

This might add some redundancy when handling interrupts for
engines that might not exist in every tile, but helps to keep the
code cleaner and more understandable.
