Input: sentelic - report device's production serial number
Hardware since Cx supports an unique identity (used to identify OEM vendors and released lot number) which is very helpful for diagnostic purpose. This revision tries to make it as a part of driver boot up message. Whilst here, also bumping fsp_drv_ver to acknowledge recent addition of absolute coordinates output.
