Hotfix for AMD UMC probing

[cyring]

hotfix_AMD_UMC_probing branch is fixing the max number of UMC to query.

This hotfix is fixing an issue of corefreqk.ko which attempts to read more than available addresses.

This hotfix is so far limiting to one UMC probing but I believe EPYC and Threadripper need more. Max UMC can be adapted consequently but I need your tests on all families, starting from Zen v1

1. Get and build the hotfix branch

git branch -f hotfix_AMD_UMC_probing origin/hotfix_AMD_UMC_probing
git checkout hotfix_AMD_UMC_probing
make clean all

2. Start CoreFreq
   version is 1.90.2

3. Post your CLI output in this thread

corefreq-cli -s -n -m -n -M

Thank you
