[PATCH v3 2/4] dt-bindings: phy: qcom,qcs615-qmp-usb3-dp-phy: Add support for Shikra

[Pratham Pratap <pratham.pratap@oss.qualcomm.com>]

From: Krishna Kurapati <krishna.kurapati@oss.qualcomm.com>

Declare the USB QMP Phy present on Shikra SoC. On this SoC, although
there are DP registers, the required internal pins have been removed
and hence DP wouldn't be operational.

Shikra needs 3 resets (dp/ phy/ phy_phy) to be asserted and de-asserted
as per hardware recommendation. Extend the bindings to accommodate the
additional reset.

Use QCS615 as a fallback since the software interface is compatible with
Shikra.
