Alexander Shishkin 76e7a91ec9 intel_th: Disallow multi mode on devices where it's broken 
[ Upstream commit 397c7729665a3b07a7b4ce7215173df8e9112809 ]

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.
