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.
