arm64: dts: rockchip: fix hdmi cec on rock-3a
HDMI CEC is configured to select HDMITX_CEC_M0 function of GPIO0_C7 by
default in rk356x.dtsi. On Radxa ROCK 3 Model A it is routed to
HDMITX_CEC_M1 according to board schematic [1].
Fix HDMI CEC by overriding pinctrl in hdmi node to select HDMITX_CEC_M1.
