platform/x86: int3472: Add new skl_int3472_gpiod_get_from_temp_lookup() helper
Add a new skl_int3472_gpiod_get_from_temp_lookup() helper.
This is a preparation patch for removing usage of the deprecated
gpiod_toggle_active_low() and acpi_get_and_request_gpiod() functions.
[hdegoede@redhat.com] use the new skl_int3472_fill_gpiod_lookup() helper
