Add support for per-CCD temperature monitoring on Zen 5 Turin (EPYC 9005)
CPUs, as they fall in a different model range with a larger number of
maximum CCDs compared to their desktop counterparts. Tested and working
on an EPYC 9555P.

Sashiko has a point, showing that the temperature of the additional four dies
can not be shown due to the code in k10temp_read_temp().

So how does your test result actually look like ?
