usb: musb: host: rely on port_mode to call musb_start()
Currently, we're calling musb_start() twice for DRD ports
in some situations. This has been observed to cause enumeration
issues after suspend/resume cycles with AM335x.
In order to fix the problem, we just have to fix the check
on musb_has_gadget() so that it only returns true if
current mode is Host and ignore the fact that we have or
not a gadget driver loaded.
Fixes: ae44df2e21b5 (usb: musb: call musb_start() only once in OTG mode)
