perf arch events: Fix duplicate RISC-V SBI firmware event name
Currently, the RISC-V firmware JSON file has duplicate event name "FW_SFENCE_VMA_RECEIVED". According to the RISC-V SBI PMU extension[1], the event name should be "FW_SFENCE_VMA_ASID_SENT". Before this patch: $ perf list firmware: fw_access_load [Load access trap event. Unit: cpu] fw_access_store [Store access trap event. Unit: cpu] .... fw_set_timer [Set timer event. Unit: cpu] fw_sfence_vma_asid_received [Received SFENCE.VMA with ASID request from other HART event. Unit: cpu] fw_sfence_vma_received [Sent SFENCE.VMA with ASID request to other HART event. Unit: cpu] After this patch: $ perf list firmware: fw_access_load [Load access trap event. Unit: cpu] fw_access_store [Store access trap event. Unit: cpu] ..... fw_set_timer [Set timer event. Unit: cpu] fw_sfence_vma_asid_received [Received SFENCE.VMA with ASID request from other HART event. Unit: cpu] fw_sfence_vma_asid_sent [Sent SFENCE.VMA with ASID request to other HART event.
