ARM: dts: imx50: Add PHY node for usbotg and adjust clocks

Browse source

Even though the ChipIdea USB controller binding[1] doesn't specify the
properties that reference a PHY as required, the Linux driver
requires[2] such a reference.

The clock situation is like on i.MX53: The USB controller is clocked
from IMX5_CLK_USBOH3_GATE and the PHY from IMX5_CLK_USB_PHY1_GATE.
