There is a timeout failure been found during stress tests. If the firmware generates a mailbox response right after driver clears the mailbox channel interrupt register, the hardware will not generate an interrupt for the response. This causes the unexpected mailbox command timeout. To handle this failure, driver checks the interrupt register before exiting mailbox_rx_worker(). If there is a new response, driver goes back to process it.
