ARM: UniPhier: reset on-board devices on start-up
If a support card is attached to the main board, the on-board
SMSC9118 LAN controller is available. It must be kept in reset
state for a while on start-up.
When the board is kicked via a debbuger rather than pushing the
hardware reset button, on-board chips are not reset; in this case
the reset signals should be asserted by software.
