USB: gadget: gadget_is_{dualspeed,otg} predicates and cleanup
This adds two small inlines to the gadget stack, which will often evaluate to compile-time constants. That can help shrink object code and remove #ifdeffery. - gadget_is_dualspeed(), currently always a compile-time constant (depending on which controller is selected). - gadget_is_otg(), usually a compile time "false", but this is a runtime test if the platform enables OTG (since it's reasonable to populate boards with different USB sockets). It also updates two peripheral controller drivers to use these: - fsl_usb2_udc, mostly OTG-related bugfixes: non-OTG devices must follow the rules about drawing VBUS power, and OTG ones need to reject invalid SET_FEATURE requests. - omap_udc, just scrubbing a bit of #ifdeffery. And also gadgetfs, which lost some #ifdefs and moved to a more standard handling of DEBUG and VERBOSE_DEBUG. The main benefits come from patches which will follow.
