[PATCH] usb: select NOP_USB_XCEIV by drivers that require it

[Michal Suchanek]

Hello,

I was updating my config by make oldconfig for a while and noticed that my USB
OTG controller is not working. Apparently it grew dependency on NOP_USB_XCEIV
over time.

Looking through defconfigs some have it included and some which seem in need of
it don't.

Since the dependency is not obvious I think it would be better to select it
where possible.

Attaching a patch.

Thanks

Michal

NOP_USB_XCEIV is non-obvious dependency for MUSB and other drivers.

This is a virtual driver in the sense that there is no actual piece of
hardware you can point at and say you did not include driver for this so
it won't work.

So just change all depends on it to select.
