[PATCH v3 2/5] arm64: dts: ls1088a: add missing PMU node

[Mathew McBride]

The Performance Manager Unit was not described in the DTS
which meant performance event monitoring was not possible.

This was exposed by a change to the PMU handling in KVM
in 5.11-rc3 which now prevents a PMU being exposed to a
guest when the host does not provide one:
"KVM: arm64: Don't access PMCR_EL0 when no PMU is available"
