List of fixes:
 - Fix "intel,vm-map" property to be optional.
 - Fix VM sensor allocation when "intel,vm-map" not defined.
 - Fix multi-channel voltage reading.
 - Fix voltage equation for negative source input.
 - Modify the temperature equation according to series 5 datasheet.
 - Fix coding style issue.

List of new features:
 - Modify "reset" property to be optional.
 - Add optional "moortec,vm-active-channels" property to define the number
   of active channels per VM.
 - Add support for mr76006 pre-scaler to multiply the voltage result by 2.
 - Add support for series 6 temperature equation.
 - Add coefficient properties to fine tune the temperature equation.
 - Add debugfs to read and write temperature coefficients

---------

Changes between v3 and v4:
*) Provide a Fixes tag for all fixes in the series.
*) Start series with fixes.
*) New patch to add description in moortec,mr75203.yaml.
*) New patch to add moortec to vendor-prefixes.
*) Fix moortec,mr75203.yaml checker errors.
*) Remove validation of device-tree parameters.
*) Fix per patch specific comments (detailed in each patch).

Changes between v2 and v3:
*) Add "moortec" prefix to all new device-tree properties.
*) Change order of patches.
*) Add explanations to better understand the changes.
*) Change "reset" property to be optional and remove the
  "reset-control-skip" property.
*) Split the patch for "fix multi-channel voltage reading" to two
   patches.
*) Change pre-scaler property format and fix typo (scalar --> scaler).
*) Fix voltage equation to support negative values instead of limiting
   value to zero.
*) Temperature equation - protect from overflow and add clamping.
*) Add new "moortec,ts-series" property to select between temperature
   equation of series 5 or series 6.

Changes between v1 and v2:
 *) Fix compilation error for patch 08/16:
    "warning: ISO C90 forbids variable length array"
