Guenter Roeck bb613ebca4 Ensure that pwm control cache is current before updating values 
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.

Guenter Roeck 2c50189d95 Improve IT8622 support 
Configuration registers on ITE8622 are different to 8620 and 8628 and
require special handling. Also, the chip supports up to 5 pwm controls.

Guenter Roeck ea3105845e Add feature flags for fan count and 16-bit fan configuration 
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.

Guenter Roeck c2ad416240 Add support for IT8781F 
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.
