We need a pm_runtime_get_sync() call from within musb_gadget_pullup() to make sure registers are accessible at that time. The problem is that musb_gadget_pullup() is called with IRQs disabled and, because of that, we need to tell pm_runtime that this pm_runtime_get_sync() is IRQ safe. We can simply add pm_runtime_irq_safe(), however, because we need to make our read/write accessor function pointers have been initialized before trying to use them. This means that all pm_runtime initialization for musb_core needs to be moved down so that when we call pm_runtime_irq_safe(), the pm_runtime_get_sync() that it calls on the parent, won't cause a crash due to NULL musb_read/write accessors.
