Subject: [PATCH] remoteproc: report firmware name on load failures

remoteproc error messages like:
  remoteproc remoteproc0: request_firmware failed: -2
  remoteproc remoteproc1: request_firmware failed: -2
are difficult to debug as one actually have no clue which device
reported it and which firmware is missing.  Be verbose and print the
name of the failed firmware.
