Subject: [PATCH/RFC 16/17] ALSA: ice1724: Use bitfield helpers

Use the field_{get,prep}() helpers, instead of open-coding the same
operations.

Signed-off-by: Geert Uytterhoeven <geert+renesas@...der.be>
---
Compile-tested only.
Marked RFC, as this depends on [PATCH 01/17], but follows a different
path to upstream.
