This patch move the reset function from initialization to

the ftgmac100 will be still supplied power after the system has been
shut-down by Linux. Hence the register used by linux won't be clear

The origin ftgmac100 driver in u-boot will only register
driver and functions to network stack and won't reset the ftgmac100
hardware if the network won't be used during boot-up.
This will lead ftgmac100 continue receiving packets and then might corrupt
