Joseph Koshy e829eb6d61 - Separate PMC class dependent code from other kinds of machine
dependencies.  A 'struct pmc_classdep' structure describes operations
  on PMCs; 'struct pmc_mdep' contains one or more 'struct pmc_classdep'
  structures depending on the CPU in question.

  Inside PMC class dependent code, row indices are relative to the
  PMCs supported by the PMC class; MI code in "hwpmc_mod.c" translates
  global row indices before invoking class dependent operations.

- Augment the OP_GETCPUINFO request with the number of PMCs present
  in a PMC class.

- Move code common to Intel CPUs to file "hwpmc_intel.c".

- Move TSC handling to file "hwpmc_tsc.c".
