[PATCH v5 10/12] arm64: dts: rockchip: rk3588s-nanopi-r6: add comment about gmac phy-mode

[Joachim Eastwood via B4 Relay]

From: Joachim Eastwood <joachim.eastwood at gmail.com>

Add comment to explain rgmii-rxid phy-mode usage. Note that the actual
delay in ns is not known. The tx_delay value of 0x42 comes from vendor
DT.
