arm64: dts: ls1046ardb: set RGMII interfaces to RGMII_ID mode
commit d79e9d7c1e4ba5f95f2ff3541880c40ea9722212 upstream.
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.
Since commit 1b3047b5208a80 ("net: phy: realtek: add support for
configuring the RX delay on RTL8211F") the Realtek 8211F PHY driver
has control over the RGMII RX delay and it is disabling it for
RGMII_TXID. The LS1046ARDB uses two such PHYs in RGMII_ID mode but
in the device tree the mode was described as "rgmii".
Changing the phy-connection-type to "rgmii-id" to address the issue.
