perf vendor events intel: Fix broadwellde tma_info_system_dram_bw_use metric 

[ Upstream commit 3779416eed25a843364b940decee452620a1de4b ]

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:
https://github.com/intel/perfmon/pull/111
