Fan noise is one of the top complaints reported. The existing
interpolation and smoothing logic has not sufficiently addressed the
issues with fans changing speeds too quickly in response to rapid
changes in thermals (particularly from PECI).
This behavior can be observed by with very basic tasks, such as:
- Powering on a system and logging into GNOME
- Starting a GUI application such as Firefox
Replace them with a fixed step update per event interval. Fans now have
a maximum amount they change change over time (3.9%/sec) as they move
towards a target duty.

Replace hard-coded PWM channels with defines so the second fan on darp10
can be handled like the second fan on units with a dGPU.

SDCC 4.3.3 (terribly) reports this as an error:

Update .clang-format for LLVM 14.0, available on Ubuntu 22.04.
There is still plenty that clang-format sucks at or does wrong, so
either add some more blocks to disable it, or just put up with it.

Replace bare int types with stdint types. This was done with:
grep -rwl 'int' src/ | xargs sed -i 's/\<int\>/int16_t/g'
grep -rwl 'unsigned long' src/ | xargs sed -i 's/\<unsigned long\>/uint32_t/g'
grep -rwl 'unsigned char' src/ | xargs sed -i 's/\<unsigned char\>/uint8_t/g'
Then reverted for *main(), putchar(), and getchar().
The Arduino declarations for parallel_main() were also corrected to
match their definitions.
SDCC does *not* generate the same code in all instances, due to `int`
being treated different than `short int`.
