media: atomisp: Fix block comment coding style in sh_css_param_shading.c

Fix checkpatch.pl warnings in sh_css_param_shading.c regarding block
comment formatting.

The warning was:
- Block comments use a trailing */ on a separate line

This change also moves text from the first line of block comments to
subsequent lines to adhere to the standard Linux kernel coding style.
