[smsc95xx] Enable LEDs

The LED pins are configured by default as GPIO inputs.  While it is
conceivable that a board might actually use these pins as GPIOs, no
such board is known to exist.

The Linux smsc95xx driver configures these pins unconditionally as LED
outputs.  Assume that it is safe to do likewise.
