In some situations the GPIO pad numbers used by the OS are not contiguous and coreboot must provide a way for ACPI to provide the expected GPIO number to the OS. To do this each GPIO group can now have a pad base value, which will be used as the starting pin number for this group and it is added to the relative pin number of this GPIO to compute the ACPI pin number for a particular GPIO. By default this change has no effect because the existing uses of INTEL_GPP() will set the pad base to PAD_BASE_NONE and the GPIO number is used as the ACPI pin number without translation.
