ENGR00163040 - FEC : Fix ethernet cannot work after system sleep.

- Descript:
  Ethernet can't work in uboot and kernel DHCP throught press
 'reset' key when send sleep command 'echo mem > /sys/power/state'
- Cause:
  FEC driver will power down phy when system sleep. If just reset the
  board, FEC driver cannot run resume function. So, need power on phy
  in uboot and linux driver.
