iio: pressure: dps310: simplify scale factor reading

Browse source

Both functions `dps310_get_pres_precision` and
`dps310_get_temp_precision` provide the oversampling rate by calling the
`BIT()` macro. However, to look up the corresponding scale factor, we
need the register value itself. Currently, this is achieved by undoing
the calculation of the oversampling rate with `ilog2()`.

Simplify the two functions for getting the scale factor and directly
use the register content for the lookup.
