x86: Mark various structures and functions as 'static'

Mark a couple of structures and functions as 'static', pointed out by Sparse:

  warning: symbol 'bts_pmu' was not declared. Should it be static?
  warning: symbol 'p4_event_aliases' was not declared. Should it be static?
  warning: symbol 'rapl_attr_groups' was not declared. Should it be static?
  symbol 'process_uv2_message' was not declared. Should it be static?
