Rob Herring (Arm) 81e15ca3e5 perf: arm_pmuv3: Avoid assigning fixed cycle counter with threshold
If the user has requested a counting threshold for the CPU cycles event,
then the fixed cycle counter can't be assigned as it lacks threshold
support. Currently, the thresholds will work or not randomly depending
on which counter the event is assigned.

While using thresholds for CPU cycles doesn't make much sense, it can be
useful for testing purposes.

Fixes: 816c267544 ("arm64: perf: Add support for event counting threshold")
