[PATCHv6 8/8] usb: dwc2: move usb_disabled() call to host driver only

[dinguyen]

From: Dinh Nguyen <dinguyen@xxxxxxxxxxxxxxxxxxxxx>

Now that platform.c will get built for both Host and Gadget, if we leave the
usb_disabled() call in platform.c, it results in the following build error
when (!USB && USB_GADGET) condition is met.

ERROR: "usb_disabled" [drivers/usb/dwc2/dwc2_platform.ko] undefined!

Since usb_disabled() is mostly used to disable USB host functionality, move
the call the host portion for the DWC2 driver.
