arm64: dts: rockchip: io-domian all default set 3.3V for rk356x boards

Browse Source 
io-domian  default as:
&pmu_io_domains {
     status = "okay";
     pmuio2-supply = <&vcc3v3_pmu>;
     vccio1-supply = <&vccio_acodec>;
     vccio3-supply = <&vccio_sd>;
     vccio4-supply = <&vcc_3v3>;
     vccio5-supply = <&vcc_3v3>;
     vccio6-supply = <&vcc_3v3>;
     vccio7-supply = <&vcc_3v3>;
};
TODO:
Need to be modified according to the actual hardware
for example rk3568-evb:
&pmu_io_domains {
     status = "okay";
     pmuio2-supply = <&vcc3v3_pmu>;
     vccio1-supply = <&vccio_acodec>;
     vccio3-supply = <&vccio_sd>;
     vccio4-supply = <&vcc_1v8>;
     vccio5-supply = <&vcc_3v3>;
     vccio6-supply = <&vcc_1v8>;
     vccio7-supply = <&vcc_3v3>;
};

/*
* There are 10 independent IO domains in RK3566/RK3568, including PMUIO[0:2] and VCCIO[1:7].
* 1/ PMUIO0 and PMUIO1 are fixed-level power domains which cannot be configured;
* 2/ PMUIO2 and VCCIO1,VCCIO[3:7] domains require that their hardware power supply voltages
* must be consistent with the software configuration correspondingly
* a/ When the hardware IO level is connected to 1.8V, the software voltage configuration
* should also be configured to 1.8V accordingly;
* b/ When the hardware IO level is connected to 3.3V, the software voltage configuration
* should also be configured to 3.3V accordingly;
* 3/ VCCIO2 voltage control selection (0xFDC20140)
* BIT[0]: 0x0: from GPIO_0A7 (default)
* BIT[0]: 0x1: from GRF
* Default is determined by Pin FLASH_VOL_SEL/GPIO0_A7:
* L:VCCIO2 must supply 3.3V
* H:VCCIO2 must supply 1.8V
