The existing regmap_update_bits_*() helpers are macros too, so I tried
to stay consistent. Any reason why they are macros and not static
inlines? If there's none, then why not convert them too? Otherwise
we'd have a static inline expanding a macro which in turn is calling a
function (regmap_update_bits_base()).
