101d2171e1 arm: am57xx: cl-som-am57x: Use new pinctrl macros
Commit 6ae4c3efbd ("ARM: DRA7: Add pinctrl register definitions")
has added new macros for pinmux configuration in line with the
kernel definitions. Fixup the current pinctrl data for the CompuLab
CL-SOM-AM57x board to use these new macros to facilitate the removal
of the old macros.

NOTE:
The PEN and PDIS macro values used previously were actually defined
inversely, a value of 1 in bit position 16 actually means that the
internal pullup/pulldown is disabled and not enabled as inferred by
PEN. So, previous pinmux config data such as (PDIS | PTU) is confusing
as it actually was meant for enabling internal pullup. The data is
fixed up only to be equivalent to the previous data.

fc300e2c5d 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
