The mode selection for the DWC3 is kind of obsolete. The driver does not
have to be host only or gadget only. This choice is confusing.
All the remaining callers of dwc3_uboot_init() explicitly set dr_mode
before calling the function, so none rely on a default behavior.
Remove the choice menu and keep only the USB_DWC3_GADGET option. Enable it
by default if USB_GADGET and USB_DWC3 are enabled.
It must be disabled for the evb-rk3328 and odroid-n2 as it uses DWC2 for
the gadget and DWC3 for the host.

This patch applies on top of git://git.denx.de/u-boot-usb.git master
This patch was a part of a larger series. The changes since are:
- Fix the test of the USB_DWC3_GADGET option. IS_ENABLED() requires the
whole option name including the 'CONFIG_' prefix
- disable the CONFIG_USB_DWC3_GADGET option for the new odroid-n2 config
