Subject: [PATCH] dt-bindings: usb: ci-hdrc-usb2: allow multiple PHYs

Qualcomm MSM8974 comes with USB HS phy in two variants, although final
DTS chooses only one.  Allow such combination in the ChipIdea USB2
bindings and also disallow any other properties in the ulpi node.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

DTS will be fixed separately.
