env: ti: j721e-evm: Add env variable to power on & reset QSGMII PHY in J7200 EVM

Browse source 
MAIN CPSW0 requires the PHY to be powered on and reset for QSGMII
operation. Add a env variable to configure driving "0" on ENET_EXP_PWRDN
controlled by GPIO EXPANDER2 (I2C Addr: 0x22), PIN: 17 and driving "1"
on ENET_EXP_RESETZ controlled by GPIO EXPANDER2 (I2C Addr: 0x22),
PIN: 18.
