This add support PHY of SMSC. 
Following phy can be used by set CONFIG_PHY_SMSC to config.
 - SMSC LAN8700
 - SMSC LAN8710/LAN8720
 - SMSC LAN8710/LAN8720

A setup of PHY was copied from linux kenrel.

This patch was not white-space-clean. Checkpatch reported 2 x  ERROR:
trailing whitespace

Fixed when applying.   I also changed the subject and commit messahe a
tiny bit.
