remoteproc: add debugfs entry to print the firmware version info
A debugfs entry called "version" is created under the corresponding
remoteproc directory when the firmware image is processed. The
design relies on the ELF baseimage having a special ELF section
with the name '.version'. The version info has to be stored into
this section in the remote processor image build step.
A read on the entry will print the contents of the version section.
The following shows an example usage:
cat /d/remoteproc/remoteproc0/version
