[PATCH/RFC 05/17] bus: omap_l3_noc: Use bitfield helpers

[Geert Uytterhoeven]

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

Signed-off-by: Geert Uytterhoeven <geert+renesas at glider.be>

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