Adding a filter constraint for Intel Skylake CHA event
UNC_CHA_UPI_CREDITS_ACQUIRED (0x38).
The event supports core-id/thread-id and link filtering.
Could you also comment on the other CHA patch?

Now, there is a recommended way in uncore document to query the number
of CHAs by reading bits 27:0 in the CAPID6 register located at Device
30, Function 3, Offset 0x9C.
I have implemented a patch and sent it to Gary. It should fix his issue.
Thanks,
Kan
