Calculating diffs with *unsigned* integers will always produce the
correct result, as long as the diff is less than the type max.
For example, suppose we read 254 and 2 for an 8 bit value:
2 - 254 = 4
Using this property, simplify diffs on time_get() comparisons.

ecflash has no verification for the EC it detects. It will attempt to
read and erase whatever it finds, where it will hang. Document what it
*should* read and an example of what it *shouldn't* read.

Explicitly affix the literal with `U` so SDCC will directly call
`moduint()` instead of `modsint()`.

Use u8/u16 instead of i16 as the value will never be negative and the
bounds are known at compile time.
Use a decrementing loop as SDCC generates more efficient code.

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`.

Most of the code is the same between IT8587E and IT5570E.
Identical files were detected with:
diff -rs src/ec/it8587e/ src/ec/it5570e/ | egrep '^Files .+ and .+ are identical$'
Then manually moved from one variant and deleted from the other.

Per the specs, a 16-byte signature is stored at 0x40. All proprietary EC
ROMs store a space-padded 16-byte vendor string at 0x50, but it isn't
required.

* SMOOTH_FANS, SMOOTH_FANS_UP, SMOOTH_FANS_DOWN build flags to smooth fan speed changes.
Defaults 40, set SMOOTH_FANS=0 to disable and keep sharp fan speed changes
* fix for ACPI CPU temperature
* allow for a floor to be set for fan smoothing and specifically configure oryp6/7 to start smoothing at 25% to mitigate fan buzzing below 25%
* update default config values for fans
* update all devices to use defaults for heatup, cooldown, update galp5 fan curves
* Decrease default cooldown time from 20 to 10
