The omap musb front-end calls into the phy driver directly
instead of using a generic phy interface, which causes a link

reset notifier to dwc3 but while at it, it removed
a spin_lock() from dwc3_reset_gadget() which might
cause an unbalanced spin_unlock() further down the line

The isp1760 driver registration function returns an error if USB is
disabled. This made sense when the driver only supported host
controllers, but now that it supports peripheral controllers host
support isn't mandatory anymore.

Fix this by returning an error only when both the HCD and UDC functions
are disabled, either through the kernel configuration or at runtime.
