[PATCH RESEND] perf/x86/intel: Bit 13 is valid for Icelake MSR_OFFCORE_RSP_x register

[Yunying Sun]

>From Intel SDM, bit 13 of Icelake MSR_OFFCORE_RSP_x register is valid for
counting hardware generated prefetches of L3 cache. But current bitmasks
in driver takes bit 13 as invalid. Here to fix it.

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
