Pull pwm fixes from Uwe Kleine-König:
 "A set of fixes for pwm core and various drivers

  The first three patches handle clk_get_rate() returning 0 (which might
  happen for example if the CCF is disabled). The first of these was
  found because this triggered a warning with clang, the two others by
  looking for similar issues in other drivers.

  The remaining three fixes address issues in the new waveform pwm API.
  Now that I worked on this a bit more, the finer details and corner
  cases are better understood and the code is fixed accordingly"
