[PATCH v2] arm64: dts: rockchip: orangepi-5: fix PCIe 3.3V regulator voltage

The vcc3v3_pcie20 fixed regulator powers the PCIe device-side 3.3V rail
for pcie2x1l2 via vpcie3v3-supply. The DTS mistakenly set its
regulator-min/max-microvolt to 1800000 (1.8 V). Correct both to 3300000
(3.3 V) to match the rail name, the PCIe/M.2 power requirement, and the
actual hardware wiring on Orange Pi 5.
