-------------------------------------------------

Current mbigen driver uses module_platform_driver() to call init function, but pl011 driver uses arch_initcall(). So pl011 driver will init earlier than mbigen driver and pl011 will get irq failed. This will happen on Hi1616.

Fix this problem by using arch_initcall in mbigen driver.
