USB_OTG initially depended on USB_SUSPEND, which was later turned into
PM_RUNTIME and finally into PM. I don't know at what point the dependency
became unnecessary but it appears to work fine without CONFIG_PM now.

However, we get lots of warnings in randconfig kernels like:

warning: (USB_OTG_FSM && FSL_USB2_OTG && USB_MV_OTG) selects USB_OTG which has unmet direct dependencies (USB_SUPPORT && USB && PM)

whenever CONFIG_PM is disabled and something else selects USB_OTG.
Let's just drop the dependency to avoid the warnings.
