The same as Sapphire Rapids, Granite Rapids also supports the discovery
table feature. All the basic uncore PMON information can be retrieved
from the discovery table which resides in the BIOS.
There are 4 new units are added on Granite Rapids, b2cmi, b2cxl, ubox,
and mdf_sbo. The layout of the counters is exactly the same as the
generic uncore counters. Only add a name for the new units. All the
details can be retrieved from the discovery table.
The description of the new units can be found at
https://www.intel.com/content/www/us/en/secure/content-details/772943/content-details.html
The other units, e.g., cha, iio, irp, pcu, and imc, are the same as
Sapphire Rapids.
Ignore the upi and b2upi units in the discovery table, which are broken
for now.
