This driver never used the older SIMPLE_DEV_PM_OPS() but instead just
set two of the callbacks directly.  Skip that deprecated macro and go
straight to the new form that avoids the need for guarding or marking
callbacks __maybe_unused.

It is possible there is some subtle reason why only two of the
callbacks normally set by SIMPLE_DEV_PM_OPS() are set. As such,
this one needs some closer reading than many of the others.
