The xe_irq_postinstall() never actually gets called after installing the interrupt handler. This oversight seems to get papered over due to the fact that the (misnamed) xe_gt_irq_postinstall does more than it really should and gets called in the middle of the GT initialization. The callstack for postinstall is also a bit muddled with top-level device interrupt enablement happening within platform-specific functions called from the per-tile xe_gt_irq_postinstall() function. Clean this all up by adding the missing call to xe_irq_postinstall() after installing the interrupt handler and pull top-level irq enablement up to xe_irq_postinstall where we'd expect it to be. The xe_gt_irq_postinstall() function is still a bit misnamed here; an upcoming patch will refocus its purpose and rename it. v2: - Squash in patch to actually call xe_irq_postinstall() after installing the interrupt handler.
