ARC: perf: don't bail setup if pct irq missing in device-tree
Current code inadventely bails if hardware supports sampling/overflow
interrupts, but the irq is missing from device tree.

| # perf stat -e cycles,instructions,major-faults,minor-faults ../hackbench
| Running with 10 groups 400 process
| Time: 0.921
|
| Performance counter stats for '../hackbench':
|
| <not supported> cycles
| <not supported> instructions
| 0 major-faults
| 8679 minor-faults
This need not be as we can still do simple counting based perf stat.
This unborks perf on HSDK-4xD
