regulator: pca9450: Use devm_register_sys_off_handler
With module test, there is error dump:
------------[ cut here ]------------
notifier callback pca9450_i2c_restart_handler already registered
WARNING: kernel/notifier.c:23 at notifier_chain_register+0x5c/0x88,
CPU#0: kworker/u16:3/50
Call trace:

__driver_probe_device+0xa0/0x150

__device_attach_driver+0xd4/0x12c
So use devm_register_sys_off_handler to let kernel handle the resource
free to avoid kernel dump.
