perf vendor events amd: Restrict model detection for zen1 based processors
This patch changes the previous blanket detection of AMD Family 17h processors to be more specific to Zen1 core based products only by replacing model detection regex pattern [[:xdigit:]]+ with ([12][0-9A-F]|[0-9A-F]), restricting to models 0 though 2f only. This change is required to allow for the addition of separate PMU events for Zen2 core based models in the following patches as those belong to family 17h but have different PMCs. Current PMU events directory has also been renamed to "amdzen1" from "amdfam17h" to reflect this specificity. Note that although this change does not break PMU counters for existing zen1 based systems, it does disable the current set of counters for zen2 based systems. Counters for zen2 have been added in the following patches in this patchset.
