This clean up series to NFC drivers that are using GPIOs on ACPI enabled platforms. Since GPIO ACPI library goes stricter about requesting resources we need to amend drivers for that. Here we are for NFC subsystem. While doing above, get rid of legacy and unused platform data as well as some artificial IDs.
