[PATCH] usb: dwc3: Set DWC3 context's mode based on selected mode.

From: Vivek Gautam
Date: Sat Mar 02 2013 - 08:27:35 EST


Now that machines may select the mode of working of DWC3 (HOST only,
GADGET only or DUAL_ROLE), lets set DWC3 mode based on that
rather than fixing it to whatever DWC3 hardware says.
This way we can skip initializing Gadget/Host in case
we are using Host-only/Gadget-only mode respectively.

selected mode in machine, rather than programming PrtCapDir
