This is a collection fixes / cleanups for the coresight driver.

Patches 1-5 are fixes, and the remaining patches are clean ups.

Changes since V2:
 - Added a patch to limit the trace data
 - Added a patch to fix tmc_read_unprepare_etr (another crash)
 - Split the patch to remove erraneous dma_free_coherent.
 - Use consistent error message format for coresight_timeout cleanup.
 - Fixed checkpatch warnings on the commit description, there are
   some errors reported on the "crash output" in the commit description.
   May be the checkpatch needs to be fixed ?
