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.
