soc: mediatek: cmdq: Use mailbox rx_callback instead of cmdq_task_cb
rx_callback is a standard mailbox callback mechanism and could cover the function of proprietary cmdq_task_cb, so use the standard one instead of the proprietary one. Client has changed to use the standard callback machanism and sync dma buffer in client driver, so remove the proprietary callback in cmdq helper.
