dtb: remove allocation for in-memory DTB
...
Replaces the `Once<Vec<u8>>` with `Once<&'static [u8]>` to avoid an
unnecessary allocation.
Adds some basic documentation.

Use HashMap rather than BTreeMap for scheme handles
...
According to the comments this previously wasn't done due to hashbrown
not having a const constructor. While it is true that HashMap::new() is
not const, HashMap::with_hasher() is const. HashMap::new() becoming
const is likely blocked on const traits.
This shrinks the kernel image by about 35kb.
