imx6_pm_stby_poweroff() only works when a pfuze is present and is
configured correctly. Calling this on every i.MX board is not nice.
What you can do is to call pfuze_register_init_callback() from here.
You'll have to add a static inline wrapper for this in case pfuze
support is not compiled in.
I wonder how this compiles as my version of this file already has a
function named imx6_init(). Using this is preferred btw as it's already
made sure that it will run only on i.MX6.

Note that this doesn't necessarily means that we are running an i.MX6.
It could be whatever else is compiled in.
