The DWC core has four interrupt signals: tx_inta, tx_intb, tx_intc, tx_intd that are triggered when the PCIe controller (when running in Endpoint mode) has sent an Assert_INTA Message to the upstream device. Some DWC controllers have these interrupt in a combined interrupt signal. Add the description of these interrupts to the device tree binding.
