arm64: dts: rockchip: keep vbus always on for usb2.0 host of rk3399

One basic condition of usb remote wakeup is vbus on, so we add
regulator-always-on property for vcc5v0_host regulator in this adds.

In the previous codes, ehci/ohci-platform did not power off
vcc5v0_host regulator due to some oddish codes, and we have fixed it
at commit b5a0a9e8794d.
