iio: pressure: hsc030pa add mandatory delay

Browse source

Add a mandatory 2ms delay between consecutive chip reads.

A Technical Note pdf specifies that the measurement cycle in these
chips takes around 1.26ms. By adding this 2ms delay we make sure that
we never get stale measurements.

For more details, please see "Figure 1" in the pdf below:
