gpio: Add support for Intel ICHx/3100/Series[56] GPIO
This driver works on many Intel chipsets, including the ICH6, ICH7,
ICH8, ICH9, ICH10, 3100, Series 5/3400 (Ibex Peak), Series 6/C200
(Cougar Point), and NM10 (Tiger Point).
Additional Intel chipsets should be easily supported if needed, eg the
ICH1-5, EP80579, etc.
Tested on QM67 (Cougar Point), QM57 (Ibex Peak), 3100 (Whitmore Lake),
and NM10 (Tiger Point).
Includes work from Jean Delvare:
- Resource leak removal during module load/unload
- GPIO API bit value enforcement
Also includes code cleanup from Guenter Roeck and Grant Likely.
