Convert Xilinx ZynqMP to DM_USB with generic DWC3 glue logic driver

Hi,

this patchset is based on unfinished series send to ML 06/13/2017 by Vignesh
"[U-Boot] [PATCH v2 00/13] driver model bring-up of dwc3 usb peripheral" We have taken some part of this to Xilinx tree and use it for a while but it is time to review it and upstream it.

The patchset has 2 patches created by Mugunthan which are a little bit fixed.
dwc3-generic driver was inspired by omap version.
And the last 3 patches just doing conversion and enable DM_USB for our platform.

Thanks,
Michal

Changes in v2:
- Retype dwc->dev in gadget.c to avoid compilation warning
- Guard udevice with __UBOOT__
- Move ifdef in core.c to avoid compilation issues for some platforms (for example edison)
- Change style to avoid correct but not nice indentation by using char *driver variable (suggested by Marek)
