Patch Review

Changes `Mmio<const SIZE: usize>` to `Mmio<T: ?Sized>`. Adds `MIN_SIZE` to `KnownSize` trait. Mostly mechanical updates to doc examples changing `Mmio<SIZE>` to `Mmio<Region<SIZE>>`.

The `MIN_SIZE` additions are sensible:
```rust
impl<T> KnownSize for T {
    const MIN_SIZE: usize = core::mem::size_of::<T>();
}
impl<T> KnownSize for [T] {
    const MIN_SIZE: usize = 0;
}
```

This is correct -- sized types have a fixed known size, slices have minimum 0.

Clean patch.
