New macro (oz_trace) is being used as pointer to "struct device *" is 
not available in all functions for dev_dbg() function.
Please let me know if there is better way to handle this, I will be 
happy to rework on this.

As well new Kconfig option was added to pass CFLAGS to compiler, so that 
dev_dbg will get compiled on system where DYNAMIC_DEBUG is not defined.
I was assuming that it is a standard practice, as I can find similar 
Kconfig option for other drivers. Or am I wrong in my understanding ?

Main idea here is to replace printk with dev_dbg(), which gives us 
option to enable individual log during runtime if DYNAMIC_DEBUG is 
enabled & provide mechanism to compile this when DYNAMIC_DEBUG is not 
enabled.

Again many of these logs will be removed in future, as currently there 
are too many logs which are not required, hence idea is to only change 
macro & then remove remaining logs in future.
