[PATCH v2 2/2] usb: misc: usb251xb: configure battery charging from DT

[Jhon Wilker Rodrigues Aquino]

From: Jhon Wilker Rodrigues Aquino <jhon.aquino@xxxxxxxxxxxxxxx>

Parse the battery-charging-enable port list from the device tree and set the corresponding bits in the hub configuration register.

Keep charging disabled by default when the property is omitted.
