From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>
Here we could use DEFINE_RUNTIME_DEV_PM_OPS() but that would have the
side effect of providing suspend and resume support. That would be
harmless but also of little purpose as this driver does very simplistic
power management with synchronous power up and down around individual
channel reads.
In general these new PM macros avoid the need to mark functions
__maybe_unused, whilst still allowing the compiler to remove them
if they are unused.
