arm64: dts: verdin-imx8mm: add otg2 pd to usbphy
The Verdin iMX8M Mini System on Module does not have USB-ID signal connected on Verdin USB_2 (usbotg2). On Verdin Development board this is no problem, as we have connected a USB-Hub that is always connected. However, if Verdin USB_2 is desired to be used as a single USB-Host port the chipidea driver does not detect if a USB device is plugged into this port, due to runtime pm shutting down the PHY. Add the power-domain &pgc_otg2 to &usbphynop2 in order to detect plugging events and enumerate the usb device.
