[PATCH] ARM: dts: am5729: beaglebone-ai: fix rgmii phy-mode

[Drew Fustini <drew@beagleboard.org>]

Since commit cd28d1d6e52e ("net: phy: at803x: Disable phy delay for
RGMII mode") the networking is broken on the BeagleBone AI which has
the AR8035 PHY for Gigabit Ethernet [0].  The fix is to switch from
phy-mode = "rgmii" to phy-mode = "rgmii-rxid".

Note: Grygorii Strashko made a similar phy-mode fix in 820f8a870f65 for
other AM5729 boards.
