Alexander Shishkin 63b7647dd0 intel_th: Disallow multi mode on devices where it's broken
[ Upstream commit 397c772966 ]

Some versions of Intel TH have an issue that prevents the multi mode of
MSU from working correctly, resulting in no trace data and potentially
stuck MSU pipeline.

Disable multi mode on such devices.
