arm: am57xx: cl-som-am57x: add ETH support
Add MAC support.
Use PHY, connected to RGMII1 as a default Eth adapter,
by appropriate setting of 'cpsw_data.active_slave'.
'cpsw_phy' env variable can override this setting.
Set the MAC addresses in the U-Boot environment.
The addresses are retrieved from the on-board EEPROM or from the SOC's
MAC fuses.
Set the following PHYs RGMII clock delays:
- Enable RX delay
- Disable TX delay
