IT8628E has 6 temperature limit registers, overlayed with VIN7..VIN9
limit registers, but only 3 temperature offset registers. Given that,
introduce separate variables for the number of temperature limit
registers and the number of temperature offset registers.

Configuration register access of the second Super-IO chip on AB350M-D3H
is just as broken as the others and can result in the known system hang-up.

This is mostly identical to IT8665E, with the exception of the
configuration bits for fans 4 and 5.

Several recent chips have a different register definition for
temperature to pwm assignment. Introduce FEAT_NEW_TEMPMAP to reflect
this and assign to affected chips.

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.
