Minas Harutyunyan 4fe4f9fecc usb: dwc2: Fix disable all EP's on disconnect
Disabling all EP's allow to reset EP's to initial state.
Introduced new function dwc2_hsotg_ep_disable_lock() which
before calling dwc2_hsotg_ep_disable() function acquire
hsotg->lock and release on exiting.
From dwc2_hsotg_ep_disable() function removed acquiring
hsotg->lock.
In dwc2_hsotg_core_init_disconnected() function when USB
reset interrupt asserted disabling all ep’s by
dwc2_hsotg_ep_disable() function.
This updates eliminating sparse imbalance warnings.

Reverted changes in dwc2_hostg_disconnect() function.
Introduced new function dwc2_hsotg_ep_disable_lock().
Changed dwc2_hsotg_ep_ops. Now disable point to
dwc2_hsotg_ep_disable_lock() function.
In functions dwc2_hsotg_udc_stop() and dwc2_hsotg_suspend()
dwc2_hsotg_ep_disable() function replaced by
dwc2_hsotg_ep_disable_lock() function.
In dwc2_hsotg_ep_disable() function removed acquiring
of hsotg->lock.
