arm64: dts: rockchip: remove the hdmi-cec pinctrl for rk3399 excavator

Browse Source 
As the edp_hpd pinctrl is reused by hdmi-cec. So the rk3399 will hit the
pinctrl register failed on bootup.

Says: the failed log:
[0.927577] rockchip-pinctrl pinctrl: pin gpio4-23 already requested by
ff940000.hdmi; cannot claim for ff970000.edp
[0.928519 ] rockchip-pinctrl pinctrl: pin-151 (ff970000.edp) status -22
[0.929112] rockchip-pinctrl pinctrl: could not request pin 151
(gpio4-23) from group edp-hpd  on device rockchip-pinctr

That will cause the edp can't work on rk3399 SoCs.

Fixes: commit
