In theory, yes.
In practise, however, it seems to be impossible to get a sysdev into the
queue that is suspended before any other sysdevs are suspended (i.e.
right after interrupts are disabled)
And then there are the platform functions. In theory, they could be done
with a regular struct device, but in practice they need to be the very
last thing before interrupts are disabled, and that again is impossible
to achieve.
