ARM: dts: am57xx-beagle-x15: use palmas-usb for USB2
The VBUS line of USB2 is connected to VBUS detect logic on the PMIC. Use the palmas-usb driver to report VBUS events to the USB driver. As the palmas-usb driver supports GPIO based ID reporting provide the GPIO for ID pin as well. Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
