Transition to using the new generic PERF_PMU_CAP_NO_INTERRUPT method for
failing a sampling event when no PMU interrupt is available.

230c4aadcc ARC: perf: ARC 700 PMU doesn't support sampling events 
The ARC 700 does not have an interrupt associated with it, and as
such it cannot trigger when a counter overflows. As the counters are
48 bit, it will usually take at least 100 days before a counter
overflows, so for mere counting of events, there is no problem.
Sampling is not supported though.

0dd450fe13 ARC: Add perf support for ARC700 cores 
This adds basic perf support for ARC700 cores. Most PERF_COUNT_HW* events
are supported now.
