[U-Boot] [U-Boot, v3, 3/3] rockchip: dts: rk3399-puma: add a 'tsd, usb-port-power' stringlist for USB1

[Philipp Tomsich]

> USB1 is connected to the on-module USB 3.0 hub and power to the hub
> (actually it's a reset signal, modeled as a fixed regulator, that will
> be released) should be enabled only during the first probing of the
> device to avoid the hub from entering its low-power mode (where it
> tries to attach on a fixed interval, but we always miss the timeslot
> when U-Boot has the controller listening).
> 
> This adds a 'tsd,usb-port-power' stringlist to enable the
> infrastructure in the board-specific usb_hub_reset_devices to find and
> control the fixed regulator associated with control of the USB hub.
