[PATCH 02/10] dt-bindings: usb: ci-hdrc-usb2: allow the HSIC PHY as the ULPI child

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

The Qualcomm HSIC USB PHY (qcom,usb-hsic-phy.yaml) is a ULPI device: its
driver is a ulpi_driver, so the PHY node must be a child of the chipidea
controller's ulpi node. The ci-hdrc-usb2 schema however hard-codes the
ULPI phy child to the qcom,usb-hs-phy.yaml schema, so any HSIC
controller instance fails validation with bogus clock/reset/compatible
errors.

Allow the ULPI phy child node to match either the HS PHY or the HSIC
PHY schema.
