Subject: [PATCH v4 0/4] usb: musb: da8xx: Fix few issues

Currently, the USB OTG of the da8xx doesn't work.
This series intend to fix them.

Change in v2:
* Fix the error path da8xx_musb_init()

Changes in v3:
* Remove the host workaround that was not working on every platform
* Add a property to the devicetree node of phy to force the phy in a specific
  mode (host or device).
* Only use dr_mode to configure the controller mode and let the phy in OTG mode.
  The main goal of this change is to prevent the phy to be set in host or
  device mode because these modes have some issues.

Changes in v4:
* Enable VBUS sense and session end comparator during probe of phy.
* Add a quirk flag to skip the phy set mode made during the init of musb.
  In that way, we can still can configure the phy mode by using mode file in
  sysfs and configure the controller mode by using dr_mode or platform_data.
* Init the phy in otg mode in da8xx glue driver.
