Suppress compiler warnings

This commit adds the allow(unused) attribute to functions and constants
that are not currently used. There is one warning remaining but
https://github.com/embassy-rs/cyw43/pull/23 attempts to address that
one. The constants have been moved into a module to allow the attribute
to be applied to the module as a whole.

The motivation for this is that it will hopefully make it easier to
spot new warnings that might be introduced by new, or updated code.
