rh: add highband spur reduction option

- When highband_spur_reduction is enabled, the lowband LO will be disabled
  during highband operation.  This improves spur performance, but also renders
  timed tune commands unusable due to the MPM call.
- A warning is logged if the user uses a timed tune command that would change
  the state of the lowband LO, as the MPM call will occur immediately instead
  of at the given command time.
