Armv8 Juno/Vexpress updates for v7.0

This contains a small set of DT updates:

1. Align DTS node naming with established coding style by replacing underscores
   with hyphens in node names. This is a safe change and does not affect ABI.

2. Add support for the CMN PMU on the Arm Morello platform, exposing the
   CMN-Skeena (CMN-600 r3p1–compatible) PMU via the standard CMN-600 binding.
   This enables PMU access on real Morello SDP hardware, where the registers
   are functional.
