[PATCH 1/9] drivers/perf: hisi: Extend struct hisi_pmu_dev_info

From: Junhao He <hejunhao3@huawei.com>

The counter bits and event range may differ from versions of a
certain uncore PMU. Make this device specific information into
struct hisi_pmu_dev_info. This will help to simplify the
initialization process by using a list of struct hisi_pmu_dev_info
rather than checking the version.
