The `_relaxed` I/O variant methods are about to be replaced by a wrapper
type exposing this access pattern with the regular methods of the `Io`
trait. Thus replace the examples to use the regular I/O methods.

Since these are examples, we want them to use the most standard ops
anyway, and the relaxed variants were but an addition that was
MMIO-specific.
