This patchset applies a general EVENT_ATTR_ID to simplify event
attributes in many PMU drivers.

Changes since v3:
- Drop changes in arm_dsu_pmu.c and hisi_uncore_pmu.c.
- Link: https://lore.kernel.org/linux-arm-kernel/1623123201-45634-1-git-send-email-liuqi115@huawei.com/

Changes since v2:
- Add _func parameter in common marcro, so string can be determined by driver.
- Link: https://lore.kernel.org/linux-arm-kernel/1621417919-6632-1-git-send-email-liuqi115@huawei.com/

Changes since v1:
- +CC maintainers of each PMU driver.
- Link: https://lore.kernel.org/linux-arm-kernel/1621322628-9945-1-git-send-email-liuqi115@huawei.com/

Similar EVENT_ATTR macros are defined in many PMU drivers,
like Arm PMU driver, Arm SMMU PMU driver. So add a generic
macro to simplify code.
