[PATCH/RFC 10/17] media: ti-vpe: cal: Use bitfield helpers

[Geert Uytterhoeven]

Use the field_prep() helper, instead of open-coding the same operation.

Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>

Compile-tested only.
Marked RFC, as this depends on [PATCH 01/17], but follows a different
path to upstream.
