[U-Boot] Enable USB host controller on Odroid-C2

[Beniamino Galvani]

Hi,

these two patches enable the USB host controller on Odroid-C2. The
first patch adds a PHY driver; the second one enables the necessary
configuration options and updates the device tree.

Note that the DWC2 driver currently does not support enabling PHYs
from the device tree and so the following series (still on review) is
needed as runtime requirement for the second patch:

 [PATCH 0/5] usb: host: dwc2: use driver model for PHY and CLOCK

Thanks,
Beniamino
