[PATCH 3/3] armv8/ls1046ardb: RGMII ports require internal delay

[Madalin Bucur]

The correct setting for the RGMII ports on LS1046ARDB is to
enable delay on both Rx and Tx so the interface mode used must
be PHY_INTERFACE_MODE_RGMII_ID. There is a pull-up that turns
on Rx internal delay by default and the u-boot does not
override that (yet) so in u-boot the interface is functional.
In Linux the PHY driver is clearing the Rx delay for the
"rgmii-txid" mode and the reception does not work.
Changing the RGMII mode to internal delay here ensures that
device tree fix-ups for the PHY connection type turn on both
Tx and Rx internal delay in Linux.

Fixes: cc1aa218f510 ("armv8/ls1046a: RGMII PHY requires internal
	delay on Tx")
