[PATCH] arm64: dts: rockchip: qnap-ts433: Simplify network PHY connection

While it requires to have the right phy driver loaded (i.e. motorcomm)
to make the phy asserting the right delays, this is generally the
preferred way to define the MAC <-> PHY connection.

Hello,

Andrew already pointed out when I posted the patch introducing the gmac0 node
that rgmii-id would be the preferred way to setup things. Back then this didn't
happen because this change broke reception of network packets. However this
only happend because I didn't have the right phy driver loaded.

Best regards
Uwe
