Add separate dwc3-qcom glue driver for Qualcomm SOCs having dwc3 core. It is needed to support peripheral mode. Patches also add support to invoke PHY runtime PM functions on host mode bus-suspend.
Changes since v2: - Addressed Rob's comments for DT binding documentation. Changes since v1: - Move dwc3 core register accesses from glue driver to dwc3 core as per review comment from Felipe. - Addressed other review comments from Felipe and Rob. - Some other minor code changes related to redability. - Add reset_control assert in driver probe to ensure core registers are reset to POR value in case of any initalization by boot code.
