  Add missing MSRs for powertop

Status in QEMU:

Bug description:
  I reported this same bug on the powertop bugtracker [1] because I
  think both projects need to change something here.

  When running powertop it crashes and prints:

    unknown op '{'
                  read_msr cpu0 0xe8 : Input/output error

  It seems that powertop is trying to access model specific registers and 
because qemu doesn't emulate them it crashes.
  Clearly powertop shouldn't crash in such case but I think it would also be 
better if qemu could add support for these registers.
