platform/x86: int3472: Parameterize LED con_id in registration

Add a con_id parameter to skl_int3472_register_led() to allow callers
to specify both the LED name suffix and lookup con_id instead of
hardcoding "privacy". This prepares for registering additional LED
types with different names.

While at it, rename the privacy LED's GPIO con_id from "privacy-led"
to "privacy" in int3472_get_con_id_and_polarity() and pass it
directly to skl_int3472_register_led(), reducing churn when adding
new LED types.

No functional change.
