Subject: [PATCH v5 14/23] EDAC/ie31200: Convert to common field_get() helper

Drop the driver-specific field_get() macro, in favor of the globally
available variant from <linux/bitfield.h>.

Signed-off-by: Geert Uytterhoeven <geert+renesas@...der.be>

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