remoteproc: add mutex protection for traces
In rproc_put() the buffers used to read remoteproc's traces were being unmapped
without any protection. If at the same time a cat on the traces is done, it
may access an unmapped buffer leading to a crash.
This patch protects the access and unmapping of dump/trace buffers with a
mutex. It also fixes some checkpatch issues in the trace functions.
