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.

Replace the log crate with a custom logging system
...
This avoids the need to explicitly set a logger early during boot, which
reduces the amount of moving parts that could go wrong slightly. And it
cuts the kernel image size by 13kb.

A bunch of things are now printed a bit more compactly or without
interleaving of logs on a single line. Also a bunch of not that useful
logs are no longer printed by default at all.
