  Log:
  Fix a few minor issues based on a bug report and reading over the HPET
  spec:
  - Use read/modify/write cycles to enable and disable the HPET instead of
    writing 0 to reserved bits.
  - Shutdown the HPET during suspend as encouraged by the spec.
  - Fail to attach to an HPET with a period of zero.
