usb: dwc3: remove dwc3 dependency on host AND gadget.
DWC3 controller curretly depends on USB && USB_GADGET.
Some hardware may like to use only host feature on dwc3,
or only gadget feature.
So, removing this dependency of USB_DWC3 on USB and USB_GADGET.
Adding the mode of operaiton of DWC3 also here
HOST/GADGET/DUAL_ROLE based on which features are enabled.
[ balbi@ti.com :
. make sure we have default modes for all possible Kernel
configurations.
. Remove the config -> menuconfig change as it's unnecessary
. switch over to IS_ENABLED() ]
