coresight: Self-hosted tracing updates for Linux v7.2

Updates for the CoreSight self hosted tracing subsystem includes:
 - Better power management for components based on the CPU PM, including
   support for components on the trace path for CPUs. Add support for
   save/restore for TRBE
 - Miscellaneous fixes to the drivers
   * Fix overflow when the buffer size is > 2GB for tmc-etr
   * Ultrasoc SMB Perf buffer OOB access
