remoteproc: qcom q6v5: fix modular build
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 see include/linux/module.h for more information ERROR: "qcom_q6v5_init" [drivers/remoteproc/qcom_q6v5_pil.ko] undefined!

ERROR: "qcom_q6v5_request_stop" [drivers/remoteproc/qcom_adsp_pil.ko] undefined! 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.
