[PATCH] soc: mediatek: mtk-svs: Explicitly include bitfield header

[Nícolas F. R. A. Prado]

Commit a92438c5a30a ("soc: mediatek: mtk-svs: Use bitfield access macros
where possible") introduced the use of FIELD_GET and FIELD_PREP macros,
which are defined in the bitfield header. Add an explicit include for it
so we're sure to have the symbols defined independently of the config.

What do we need the bits.h for?

bits.h has the definition for GENMASK(h, l), used in this file :-)

does not break. But we probably don't want to rely on that for the future.

Applied thanks.
