soc/intel/jasperlake: Publish single GPIO ACPI device
Current pin-ctrl kernel v5.4 driver expects the firmware to publish single GPIO ACPI device. Until kernel pin-ctrl driver implementation is updated to consume community based GPIO ACPI device, update the current ACPI code to comply with pin-ctrl driver requirement. BUG=b:150154277 TEST=Verify intel pin-ctrl driver can successfully load in OS Signed-off-by: Aamir Bohra <aamir.bohra@intel.com> Change-Id: Ifcc92adaee550182ab405541ea85019f31bb8658 Reviewed-on: https://review.coreboot.org/c/coreboot/+/39470 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Karthik Ramasubramanian <kramasub@google.com> Reviewed-by: Subrata Banik <subrata.banik@intel.com>
