pr_* macros replaced with dev_* as they are more preffered over pr_*.
each file which had pr_* was reviewed manually and replaced with dev_*.
here we have actually used the reference of the vortex which was added
to some functions in the previous patch of this series.

The prefix of the CARD_NAME and prefix of "vortex:" was also
removed as the dev_* will print the device name.
