Add imx8qm's own pm, otherwise the following panic will
occur during the startup process:
Kernel panic - not syncing: Asynchronous SError Interrupt
Hardware name: Freescale i.MX8QM MEK (DT)
Workqueue: events_unbound deferred_probe_work_func
Call trace:
dump_backtrace+0x98/0xf0
show_stack+0x18/0x24
dump_stack_lvl+0x60/0xac
