WIP: intel/dev: fall back to default topology values if invalid kernel data

Lionel Landwerlin requested to merge llandwerlin/mesa:review/topology-register-workaround into main

It seems some of the registers the kernel reads report invalid values. It might take a while to figure out what's going wrong and get the kernel fixed so if we detect non sense values just fallback to default values in our database.
