Reset ENET_RST_B to make ENET function stable.
Since DM_GPIO enabled, we use "gpio_spi@0_5" which corresponds to
ENET_RST_B.
This should better be handled like the kernel: the FEC driver uses the "phy-
reset-gpios" property and perform the reset.
I have not switch to enable FEC DM now. when FEC DM enabled,
I could drop this piece code.
Thanks,
Peng.
