arm: perf: add more specific platform device IDs When described in DT, PMUs are given specific compatible strings (e.g. "arm,cortex-a15-pmu") which makes it very easy to reorganise the way individual PMUs are handled (i.e. we can easily split them into separate drivers). The same is not true of PMUs described in board files, which are all use the platform_device_id "arm-pmu" and must all be handled by the same driver. To enable splitting the ARMv6, ARMv7, and XScale PMU drivers we need board files to identify which variant they provide. As a first step, this patch adds new platform_device_id values: "armv6-pmu", "armv7-pmu, and "xscale-pmu". Once board files are moved over and all existing uses of "arm-pmu" are gone, we can split the existing driver apart.
