arm64: dts: ti: k3-*: Replace rgmii-rxid with rgmii-id for CPSW ports

The MAC Ports across all of the CPSW instances (CPSW2G, CPSW3G, CPSW5G and
CPSW9G) present in various K3 SoCs only support the 'RGMII-ID' mode. This
correction has been implemented/enforced by the updates to:
a) Device-Tree binding for CPSW [0]
b) Driver for CPSW [1]
c) Driver for CPSW MAC Port's GMII [2]

To complete the transition from 'RGMII-RXID' to 'RGMII-ID', update the
'phy-mode' property for all CPSW ports by replacing 'rgmii-rxid' with
'rgmii-id'.
