[PATCH] stmmac: platform: adjust messages and move to dev level

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

This patch amendes error and warning messages across the platform driver. It
includes the following changes:
 - remove unneccessary message when no memory is available
 - change info level to warn in the validation functions
 - append \n to the end of messages
 - change pr_* macros to dev_*
