FROMLIST: usb: dwc3: qcom: Add support to skip phy management by USB core

[Prashanth K (prashk-oss)]

DWC3 driver does manage phys itself sufficiently for Qualcomm platforms. If xhci-skip-phy-init is not set, the HCD core does a phy_init and phy_ exit is done only when roothub is being destroyed. Due to this, during system suspend in host mode, although phy_exit is done by DWC3 core, the init_count on phy is never down to zero since HCD core also did an init. consequently causing phy's exit routine to not be called. Hence, add support to skip phy management by USB core.

Some Exynos platforms still do rely on USB core for phy_calibrate calls, hence disable USB core management for Qualcomm platforms only.
