Add T6050 PMP registry-v2 descriptors, DMA ownership, auxiliary endpoint startup, and bounded shutdown. Preserve the current PMP telemetry, power-vote, and other-SoC paths while adapting to the 7.3 Rust device and MMIO APIs.

Bare-metal result on the M5 Pro (J714sAP, aura Stage 2 boot chain): the existing driver's registry handling, as used for T8142, starts the T6050 PMP firmware with a T6050 entry (42-bit DMA, endpoint 7 not started; it never readies on T6050, -ETIME otherwise): "PMP firmware and endpoint ready", PMC and CLPC bind behind it. That's #1326. This PR's registry-v2 path is still the APIF guest's; on bare metal it isn't needed. Open on both paths: once running, the PMP's PMC vote stays at iBoot's DCS 5 / fabric 1 and doesn't follow bandwidth yet. 🤖 Generated with Claude Code |
