Rewrite the code to use irq_set_chained_handler_and_data() handler with
chained_irq_enter() and chained_irq_exit() processing instead of using
devm_request_irq().
advk_pcie_irq_handler() reads IRQ status bits and calls other functions
based on which bits are set. These functions then read its own IRQ status
bits and calls other aardvark functions based on these bits. Finally
generic_handle_domain_irq() with translated linux IRQ numbers are called.
