There is no phy driver that works on the Rockchip board for either USB
host port yet.  For now just hardcode the vbus signal to be on all the
time which makes both the dwc2 host and the EHCI port work.

Signed-off-by: Doug Anderson <dianders@chromium.org>

Changes in v2:
- usb_host_vbus => vcc_host to match supply name, not pin name.
- pin name now matches in name in schematic
