Subject: [PATCH v5 18/23] pinctrl: ma35: Convert to common field_{get,prep}() helpers

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

Signed-off-by: Geert Uytterhoeven <geert+renesas@...der.be>
---
v5:
  - Extracted from "bitfield: Add non-constant field_{prep,get}()
    helpers".
