sio/ite/common: Add generic environment-controller driver
The environment-controller entity is shared by many ITE super-i/o
chips. There are some differences between the chips, though. To cover
that, the super-i/o chip should select Kconfig options of this driver
accordingly.
The current implementation isn't exhaustive: It covers only those
parts that are connected on boards I could test, plus those that are
currently used by the IT8772F. The latter could be ported to use this
driver if somebody minds to test it.
