arm64: dts: rockchip: rk3588-rk806: Raise avdd_0v75_s0 voltage to 0.8375V 

HDMI has compatibility problems when the HDMI PHY VDD is set to
the nominal 0.75V. On some televisions, signal may be no recognized
when switch resolution. After actual testing, raising voltage up
to 0.8375V can solve the compatibility problems such as no signal.
