Subject: [PATCH] usb: kconfig: fix warning of select USB_OTG

When choose randconfig for kernel build, it reports below warning:
"warning: (USB_OTG_FSM && FSL_USB2_OTG && USB_MV_OTG) selects USB_OTG
which has unmet direct dependencies (USB_SUPPORT && USB && PM)"

In fact, USB_OTG is visible symbol and depends on PM, so the driver
needs to depend on it to reduce dependency problem.
