ACPI CPU driver does not support CPUs declared as Devices.

Description

On cascade lake CPUs the temperature data is not being reported either in the UI or via sysctls. It seems something needs to be merged back into 11.3 for support of cascade lake.

root@tn24b[~]# sysctl dev.cpu
sysctl: unknown oid 'dev.cpu'

Edited

Its not a problem of coretemp(4), but ACPI CPU driver, which in 11.3 supports only CPUs reported by ACPI as Processor type, while new ACPI specification started to report them as Device type and so some new BIOS'es.  MFC of one commit from head should fix the problem.
