[0/6] iio:pressure:ms5637: add ms5803 support

Hello,

This series adds support for the Measurement Specialities ms5803. It is
very similar to the ms5805 but has a different PROM layout (which I
suspect predates the ms5805 PROM layout). Also it supports less
frequency sampling options.

After a bit of preparatory work in the ms5637 driver and its common
library, mainly to handle the PROM layou and sample frequencies, adding
support is trivial.

Alexandre Belloni (6):
  iio:pressure:ms5637: switch to probe_new
  iio:pressure:ms5637: introduce hardware differentiation
  iio:pressure:ms5637: limit available sample frequencies
  iio:common:ms_sensors:ms_sensors_i2c: rework CRC calculation helper
  iio:common:ms_sensors:ms_sensors_i2c: add support for alternative PROM
    layout
  iio:pressure:ms5637: add ms5803 support
