[PATCH v1 3/6] i2c: designware: Get rid of fp_str temporary variable

[Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>]

There is better for debug purposes, easy to grep, and for reader to see
what speed we configure, if we use full name of the mode in case of Fast
Plus one. As a side effect we may get rid of temporary variable.
