feat(tc): enable MPMM

This change enables MPMM and adds, to the TC firmware configuration
device tree, the AMU counters representing the "gears" for the
Maximum Power Mitigation Mechanism feature of the Cortex-X2,
Cortex-A710 and Cortex-A510:

- Gear 0: throttle medium and high bandwidth vector and viruses.
- Gear 1: throttle high bandwidth vector and viruses.
- Gear 2: throttle power viruses only.

This ensures these counters are enabled and context-switched as
expected.
