remoteproc: qcom q6v5: fix modular build

Browse source 
The new driver only works as built-in code at the moment but fails
with a link error when configured as a loadable module:

WARNING: modpost: missing MODULE_LICENSE() in drivers/remoteproc/qcom_q6v5.o

This exports the internal symbols as needed and adds the MODULE_LICENSE()
and MODULE_DESCRIPTION() tags. I could not figure out the author, so I
did not add a MODULE_AUTHOR() tag for now.
