Renamed struct usba_udc_errata to struct usba_udc_caps, we are adding a new property which is not about errata, this way the struct is not misnamed.
New struct usba_udc_caps property: irq_single_edge_support, boolean, set to true if the board supports IRQ_TYPE_EDGE_FALLING and IRQ_TYPE_EDGE_RISING, otherwise set to false.
