perf vendor events intel: Fix broadwellde tma_info_system_dram_bw_use metric
Broadwell-de has a consumer core and server uncore. The uncore_arb PMU
isn't present and the broadwellx style cbox PMU should be used
instead. Fix the tma_info_system_dram_bw_use metric to use the server
metric rather than client.
The associated converter script fix is in:
