util/inteltool: add support for EBG (Emmitsburg) PCH

Browse Source 
EBG (Emmitsburg) PCH is used in Intel SPR-SP chipset.

Its datasheet is Intel doc# 606161.

Add Intel Emmitsburg PCH GPIO pin definitions.

Also common code change is made to support Intel Emmitsburg PCH:
a. Instead of 2 PAD registers per GPIO, it has 4 PAD registers.
b. The register address space may not be contiguous from one GPIO
group to the next GPIO group.
