rust: io: register: remove relative registers

Relative registers can be better served by projection to subregion instead
of ad-hoc handling in register macro. Projection composes better (e.g. it
natively allows relative registers of relative registers without needing
additional support).

Remove relative register support, and update the documentation to
demonstrate how projection and subregions can be used to achieve this
instead.
