Subject: [PATCH v4 09/16] sound: cs35l41: Enable Internal Boost in shared lib

Internal Boost enable is the default option from reset, but with
external boost support, internal boost must be disabled.
Add the enable of internal boost in cs35l41_boost_config to
centralize the internal boost configuration.
