net: txgbe: Support to handle GPIO IRQs for AML devices
The driver needs to handle GPIO interrupts to identify SFP module and
configure PHY by sending mailbox messages to firmware.
Since the SFP module needs to wait for ready to get information when it
is inserted, workqueue is added to handle delayed tasks. And each SW-FW
interaction takes time to wait, so they are processed in the workqueue
instead of IRQ handler function.
