Arm firmware fixes for v7.3

SCPI fixes address resource leaks and invalid firmware responses, while
FF-A gains shutdown cleanup needed for normal kexec.

- Release the device node reference acquired during SCPI domain lookup.
- Validate SCPI DVFS OPP counts and indices returned by firmware to
  prevent out-of-bounds accesses and invalid clock rates.
- Register the SCPI cpufreq device only once across DVFS providers,
  preserving the registered device pointer for cleanup and allowing
  retries after registration failure.
- Run FF-A teardown during orderly shutdown so notifications, partition
  devices and RX/TX mappings are released before a replacement kernel
  boots through normal kexec.

Also includes replacing a literal platform device ID with
PLATFORM_DEVID_NONE and correcting an SCMI comment typo.
