soc/intel/cannonlake: Fix GPIO reset mapping
According to document 337348-001 (Intel® 300 Series and Intel® C240 Series Chipset Family Platform Controller Hub Datasheet - Volume 2 of 2), the only GPIOs that support PWROK reset are those in the GPD group. The mappings themselves are correct, but they're assigned to the wrong communities.
