gpiolib: acpi: Turn dmi_system_id table into a generic quirk table
commit 1ad1b54099c231aed8f6f257065c1b322583f264 upstream.
Turn the existing run_edge_events_on_boot_blacklist dmi_system_id table
into a generic quirk table, storing the quirks in the driver_data ptr.
This is a preparation patch for adding other types of (DMI based) quirks.
