[Xen-devel] [PATCH] xen/arm: Blacklist PMU with "arm, cortex-a53-pmu"

[Amit Singh Tomar <amittomer25@xxxxxxxxx>]

At the moment, we hide PMU's from domain 0 and XEN boot fails on platform[1]
where DTS contains "arm,cortex-a53-pmu" as compatible string for PMU node.

This patch simply adds "arm,cortex-a53-pmu" to list of blacklisted PMUs.
