Uwe Kleine-König 2d29aa5734 pwm: axi-pwmgen: Let .round_waveform_tohw() signal when request was rounded up 
[ Upstream commit a85e08a05b ]

The .round_waveform_tohw() is supposed to return 1 if the requested
waveform cannot be implemented by rounding down all parameters. Also
adapt the corresponding comment to better describe why the implemented
procedure is right.
