Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5d515ee40cb57ea5331998f27df7946a69f14dc3

Intel-SIG: commit 5d515ee4 perf/x86/uncore: Don't WARN_ON_ONCE() for a broken discovery table
Backport SPR MCC UPI uncore discovery warning fixes to OLK-5.10.

-------------------------------------

The kernel warning message is triggered, when SPR MCC is used.

[   17.945331] ------------[ cut here ]------------
[   17.946305] WARNING: CPU: 65 PID: 1 at
arch/x86/events/intel/uncore_discovery.c:184

It's caused by the broken discovery table of UPI.

The discovery tables are from hardware. Except for dropping the broken
information, there is nothing Linux can do. Using WARN_ON_ONCE() is
overkilled.

Use the pr_info() to replace WARN_ON_ONCE(), and specify what uncore unit
is dropped and the reason.
