src/superio/ite/common: Prepare for ITE IT8786E SuperIO 

Introduce 7bit Slope PWM registers. New ITE SuperIO may have contiguous
7bit values for PWM slope.

Add option to enable External Sensor SMBus Host.

Update/add registers macros for IT8786E-F which are not backwards
compatible.

Slope PWM registers have no separate BIT6 and are set directly by
7-bit values instead.
