Move most HPET logs to the trace log level
...
This significantly reduces the amount of boot logs produced by the
kernel by default on x86. With this the full kernel boot logs now fit on
a single screen on my system.

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.
