HiSilicon's Hip09 is comprised by multi-dies that can be connected by SLLC module (Skyros Link Layer Controller), its has separate PMU registers which the driver can program it freely and interrupt is supported to handle counter overflow. Let's support its driver under the framework of HiSilicon uncore PMU driver. SLLC PMU supports the following filter functions: * tracetag_en: allows user to count data according to tt_req or tt_core set in L3C PMU. * srcid_cmd & srcid_msk: allows user to filter statistics that come from specific CCL/ICL by configuration source ID. * tgtid_hi & tgtid_lo: it also supports event statistics that these operations will go to the CCL/ICL by configuration target ID or target ID range. It's the same as source ID with 11-bit width in the SoC.
