Corruption of the MEAS_CFG register has been observed soon after
system boot. In order to recover this scenario, check MEAS_CFG if
measurement isn't ready, and if it's incorrect, reset the DPS310
and execute the startup procedure. Include a patch to move the
startup procedure into a function.

Changes since v1:
 - Separate into two patches
 - Rename 'dps310_verify_meas_cfg' to 'dps310_check_reset_meas_cfg'

Looks good to me. I'll leave this a little longer on list to give Joel
and others the opportunity to take a look.

If I seem to have lost it in a few weeks time, feel free to ping me
(it's been known to happen though I think my tracking is much less
error prone now I have moved to patchwork + my local system).
