[PATCH 07/23] arm64: zynqmp: Add pmu interrupt-affinity

From: Radhey Shyam Pandey <radhey.shyam.pandey@amd.com>

Explicitly specify interrupt affinity to avoid HW perfevents
need to guess. This avoids the following error upon linux boot:
armv8-pmu pmu: hw perfevents: no interrupt-affinity property,
guessing.
