perf/x86/intel: Fix invalid Bit 13 for Icelake MSR_OFFCORE_RSP_x register
The Intel SDM states that bit 13 of Icelake's MSR_OFFCORE_RSP_x
register is valid, and used for counting hardware generated prefetches
of L3 cache. Update the bitmask to allow bit 13.
Before:
$ perf stat -e cpu/event=0xb7,umask=0x1,config1=0x1bfff/u sleep 3
Performance counter stats for 'sleep 3':
<not supported> cpu/event=0xb7,umask=0x1,config1=0x1bfff/u
After:
$ perf stat -e cpu/event=0xb7,umask=0x1,config1=0x1bfff/u sleep 3
Performance counter stats for 'sleep 3':
9,293 cpu/event=0xb7,umask=0x1,config1=0x1bfff/u
