[PATCH 07/12] ARM: i.MX53 Vincell: Reset phy consistently from device tree

[Sascha Hauer]

The phy reset for the Vincell board is done from device tree whereas
the Vincell-LT resets the phy from board init code. Since both boards
share the same code base the regular Vincell board ends up with a
duplicated phy reset, with the second reset being done after the
FEC has been initialized.
Fix this by removing the phy reset from the board code and adding the
phy reset to the Vincell-LT dts file.
