[libcamera-devel] [PATCH v5 1/8] ipa: raspberrypi: Make device_status.h C++ only header, and update comments

[Naushir Patuck]

This header file is no longer C compatible, so remove the extern "C"
declaration.

Replace C++ style comments with C style based on libcamera guidelines.

There are no functional changes in this commit.
