[PATCH 5.16 230/285] perf/x86/intel: Update the FRONTEND MSR mask on Sapphire Rapids

[Greg Kroah-Hartman]

From: Kan Liang <kan.liang@xxxxxxxxxxxxxxx>

commit e590928de7547454469693da9bc7ffd562e54b7e upstream.

On Sapphire Rapids, the FRONTEND_RETIRED.MS_FLOWS event requires the
FRONTEND MSR value 0x8. However, the current FRONTEND MSR mask doesn't
support it.

Update intel_spr_extra_regs[] to support it.
