[PATCH v6 19/26] iio: mlx90614: Convert to common field_{get,prep}() helpers

[Geert Uytterhoeven]

Drop the driver-specific field_get() and field_prep() macros, in favor
of the globally available variants from <linux/bitfield.h>.

v6:
  - No changes,

v5:
  - Extracted from "bitfield: Add non-constant field_{prep,get}()
    helpers".
