How about 'depends on HAS_USB_DWC_OTG' then select HAS_USB_DWC_OTG in the Kconfig of the chips that have this device.
That way all the information about a given device is concentrated in its own Kconfig file and this line doesn't grow without limit as new devices add support for this driver. I know for a fact that there are several other processors supported by the kernel that have this device and they will want to add support once the driver is merged.
There are a lot of chip specific config variables below as well. Perhaps they could be rearranged in a similar manner.
