[PATCH] arm64: dts: rockchip: Change ethernet TXD timing delay value

[Dongjin Kim]

Very poor network performance is observed on the ODROID-M1 Board
(REV 1.0 20220613) when running iperf3 (under 200Mbits/sec), and
this problem can be resolved after changing the value of TXD
timing to 0x35 from 0x4f.
