mbigen: fix mbigen driver defer probe

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I56R9J
CVE: N/A

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

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.
