Subject: [PATCH 0/3] rust: select AUXILIARY_BUS instead of depending on it

I noticed this after trying to understand why my minimal Nova defconfig
was not selecting NOVA_CORE anymore and why I couldn't even find it in
menuconfig.

CONFIG_AUXILIARY_BUS cannot be enabled directly and must be selected by
another module. Options that depend on it thus cannot be enabled unless
a different module selecting AUXILIARY_BUS is also enabled.

All non-Rust modules using CONFIG_AUXILIARY_BUS select it, so it should
make sense for the Rust ones to use that scheme as well.
