PATCH 1/1 arm64: dts: rockchip: Fix USB power enable pin for BTT CB2 and Pi2

Fix typo into regulator GPIO definition. With current
definition - USB powered off. Valid definition can be found on "pinctrl" section:
vcc5v0_usb2t_en: vcc5v0-usb2t-en {
rockchip,pins = <3 RK_PD5 RK_FUNC_GPIO &pcfg_pull_none>;
};

vcc5v0_usb2b_en: vcc5v0-usb2b-en {
rockchip,pins = <4 RK_PC4 RK_FUNC_GPIO &pcfg_pull_none>;
};
