Compiler warnings/remarks

[DusanJovic-NOAA]

When we build ccpp-physics as a ufs-weather-model sub module we are required to have 0 warnings. Following is a list of warnings/remarks from a ufs-weather-model build on Hera:

All warnings must be fixed, and it would also be nice to eliminate the remarks as well.
