FSI changes for v5.18

 * Improvements in SCOM and OCC drivers for error handling and retries

 * Addition of tracepoints for initialisation path

 * API for setting long running SBE FIFO operations

* tag 'fsi-for-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/joel/fsi:
  fsi: Add trace events in initialization path
  fsi: sbefifo: Implement FSI_SBEFIFO_READ_TIMEOUT_SECONDS ioctl
  fsi: sbefifo: Use specified value of start of response timeout
  fsi: occ: Improve response status checking
  fsi: scom: Remove retries in indirect scoms
  fsi: scom: Fix error handling
