Sorry for
On some Goldmont based systems such as ASRock J3455M the BIOS may not
enable the IPC1 device that provides access to the PMC and PUNIT. In
such scenarios, the IOSS and PSS resources from the platform device can
not be obtained and result in a invalid telemetry_plt_config which is an

to meaningful values in nanosecond units of time.

Cannonlake PCH allows us to ignore LTR from more IPs than Sunrisepoint
