[PATCH 6.15 42/49] perf/arm-cmn: Fix REQ2/SNP2 mixup

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.15-stable review patch.  If anyone has any objections, please let me know.

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

From: Robin Murphy <robin.murphy@arm.com>

commit 11b0f576e0cbde6a12258f2af6753b17b8df342b upstream.

Somehow the encodings for REQ2/SNP2 channels in XP events
got mixed up... Unmix them.
