The HDMI CEC is not working correctly on Radxa ROCK 3 Model A.

This series assigns a clock rate of 32768 to hdmi cec clock and a pinctrl
to use HDMITX_CEC_M1 function of GPIO0_C7.

Please note that this series also requires a fix in the pinctrl driver to
correctly select HDMITX IO mux M1 for a fully working HDMI CEC, see [1].
