arm64: dts: rockchip: rk356x-evb: fix pcie supply to regulator-fixed

Browse Source 
The pcie supply design is (rk3566 evb2 example)
DC12V
  -> VCC12V_PCIE(controlled by GPIO0_C2_H)
  -> VCC3V3_PCIE(controlled by GPIO0_C2_H)
  -> VCC5V0_SYS
       -> VCC3V3_PI6C(controlled by GPIO0_C2_H)

The pci phy driver only want to enable or disable the VCC3V3_PCIE power.

Suggested from pcie owner to ignore the VCC12V_PCIE and VCC3V3_PI6C, so
the dts only need to add regulator node for VCC3V3_PCIE.

Most of time we keep the regulator name same as the hardware design, so
the dts node is
    vcc3v3_pcie: gpio-regulator {
        compatible = "regulator-fixed";
        regulator-name = "vcc3v3_pcie";
        regulator-min-microvolt = <3300000>;
        regulator-max-microvolt = <3300000>;
        enable-active-high;
        gpio = <&gpio0 RK_PB7 GPIO_ACTIVE_HIGH>;
        vin-supply = <&dc_12v>;
    };

The regulator type is "regulator-fixed" since its voltage always be
3.3v, min and max should be 3300000 make the regulator has a voltage
value.

The regulator can be enabled or disabled by regulator_enable or
regulator_disable function, so make the GPIO0_B7 as "ena_pin" for the
regulator.

The regulator is supplied by DCIN_12V, so add the vin-supply.
