soc/intel/common/gpio: distingiush single vs multi acpi devices
Sadly, small core and big core are not aligned with the OS driver's
expectation on the number of ACPI devices used for each community.
Big core uses a single device while small cores use one ACPI device
per community. Allow for this distinction within the common gpio
implementation and ensure apollolake is utilizing the new option
to retain the correct behavior.
