board: ti: j784s4: Add support to reset Ethernet PHY
The Ethernet PHY on the QSGMII daughtercard connected to the ENET Expansion
1 Slot on J784S4 EVM has to be powered on and reset for use by Ethernet
Switch Firmware (EthFw). This can be achieved using gpio commands.
Since EthFw has to be loaded at U-Boot on the MCU2_0 core, the
"dorprocboot" environment variable is set for such usecase. Thus, run the
commands to power on and reset the Ethernet PHY conditionally based on
the value of the "dorprocboot" variable using gpio commands.
