msm: camera: common: Reduce data section size with logging optimized

Browse Source 
Current logic of logging passes the strings as arguments to
logging Macros. This converts them into string literals and
increase the data section size.
This commit changes the logic to convert the tags into
strings inside a function, thus optimizing the data section size.
Top level estimations shows the reduction of 1.5MB .ko size.
