[PATCH 3/3] arm64: dts: rockchip: Enable PCIe controller on Radxa E20C

Hi,

The pciem1_pins contains PCIE20_PERSTn_M1 (GPIO1_A2)
This will cause conflicts, "pinctrl-0 = <&pciem1_pins>" is enough.

[    0.115608] rockchip-pinctrl pinctrl: not freeing pin 34 (gpio1-2) as part of deactivating group pciem1-pins - it is already used for some other setting
[    0.191042] rockchip-pinctrl pinctrl: pin gpio1-2 already requeste by pll_gpll; cannot claim for 140000000.pcie
[    0.191949] rockchip-pinctrl pinctrl: error -EINVAL: pin-34 (140000000.pcie)
[    0.192570] rockchip-pinctrl pinctrl: error -EINVAL: could not request pin 34 (gpio1-2) from group pciem1-pins on device rockchip-pinctrl

Missing supply: "vpcie3v3-supply = <&vcc_3v3>;"
