iio: pressure: icp10100: Switch from UNIVERSAL to DEFINE_RUNTIME_DEV_PM_OPS(). 

The suspend and resume callbacks in this driver appear to be safe
to call repeatedly, but why do so when we can use the
DEFINE_RUNTIME_DEV_PM_OPS() macro to supply callbacks that check if
we are already runtime suspended before doing unnecessary work.
