[PATCH v2 01/10] DMA, CMA: clean-up log message

We don't need explicit 'CMA:' prefix, since we already define prefix
'cma:' in pr_fmt. So remove it.

And, some logs print function name and others doesn't. This looks
bad to me, so I unify log format to print function name consistently.

Lastly, I add one more debug log on cma_activate_area().
