Kan Liang d18216fafe perf/x86/intel: Add more events requires FRONTEND MSR on Sapphire Rapids 
On Sapphire Rapids, there are two more events 0x40ad and 0x04c2 which
rely on the FRONTEND MSR. If the FRONTEND MSR is not set correctly, the
count value is not correct.

Update intel_spr_extra_regs[] to support them.
