Subject: [PATCH v4 7/9] staging: media: atomisp: replace raw pr_*() by
dev_dbg()
It is recommended to use driver model diagnostic macros dev_*() instead
of raw printk() or pr_*() since the former ensures that the log messages
are always associated with the corresponding device and driver. This also
addresses the checkpatch complain for not using KERN_<LEVEL> facility in
printk() call.

Changes since v3:
- use dev_dbg instead of dev_info since it spams less
Changes since v2:
- Tag Fabio Auito for the patch suggestion
Changes in v1:
- implement following changes suggested by Fabio Aiuto
a. use dev_info instead of pr_info
b. update patch log message accordingly
