bugfix: Guruplug: Use standard miiphy 

call to reset PHY chip.

Current PHY Software Reset operation in guruplug does not
poll reset bit in control register to go to 0(auto clearing)
for making sure reset was successful.This patch uses standard
miiphy call miiphy_reset to make sure proper PHY reset operation.
