The RGMII ports on LS1043ARDB platforms require both RX and TX internal
delays to be enabled. The device tree reports only the TX ID because the
RX ID used to be enabled by default.

With the addition of RX ID support for the Realtek 8211F PHY driver in
commit e32e4d0f58cb ("net: phy: realtek: add rx delay support for
RTL8211F"), the RX ID is disabled by the driver if not reported explicitly.
This causes the RX to no longer work.

Change the phy-connection-type for the RGMII ports to "rgmii-id" in order
to enable both RX and TX internal delays.

Fixes: be1d75896996 ("ARM: dts: add QorIQ DPAA 1 FMan v3 to LS1043ARDB")
