superio/ite/it8623e: initialize the PWM fan controller
Copies the common/env_ctrl support code from the it8728f driver. Tested on an ASUS AM1I-A using Linux 4.16.7-gentoo as payload, and booting userspace without a kexec call. Prior to this change, an error was given during boot: it87 it87.656: Detected broken BIOS defaults, disabling PWM interface After this change, the message is gone, and PWM fan control works through the /sys/class/hwmon interface.
