The ADC LSB on some newer chips such as IT8613E and IT8625E is
officially 11mV, not 10.9mV. Add support for it.

Several recent chips don't support configuration bits to turn fan control
off entirely for the first three fans. Handle all of them with a
configuration flag.

Some chips have internal voltage scaling but 10.9mV ADC,
so we can no longer associate the 12mV ADC with internal scaling
but need a different flag to distinguish scaling support.
Also fix ADC resolution for IT8790E and IT8792E.

The chip features match those of IT8790E. Most important is the
ADC resolution, which is 12 mV, not 10.9 mV.

In IT8620E, after setting pwm control to manual, it was observed that
pwm values for fan 4..6 have reversed results (writing 0 results in fans
running at full speed, writing 255 results in fans turned off).
With the new PWM control, pwm polarity for pwm control 4..6 is specified
in its pwm control registers. Those registers are overwritten when setting
the pwm mode or the temperature mapping. Do not touch bit 2..6 of pwm
control registers on register writes to fix the problem.

fan4 control is enabled if bit 2 of GPIO control register 4 is disabled,
not when it is enabled. Since the check is for the skip condition, it is
reversed. This applies to both IT8620 and IT8628.

The chip is similar to IT8732E, but supports only three fans
instead of four (the driver currently does not support the 4th
fan on IT8732E).
Note that the chip ID is 0x8733, not 0x8792 as one would expect.

If sensor attributes were never read, the pwm control data has not been
initiialized, which can cause wrong driver behavior. Ensure that cached
data is current before acting on it.

Configuration registers on ITE8622 are different to 8620 and 8628 and
require special handling. Also, the chip supports up to 5 pwm controls.

Newer chips don't typically support VID inputs or control.

Fans 4-5 are not supported on all chips and revisions. Also, 16-bit fan
counters only need to be enabled on older chips. Provide feature flags
to simplify adding support for new chips.

IT8781F is mostly compatible to IT8782F. Major difference is that it only
supports four instead of six UART channels, and therefore does not share
the uart6 pins.
