This commit adds support for dead time delay to SAMv7 PWM driver. The
dead time can be used to delay an active PWM output at the begining
of the period. This can be used for H bridge control for example.
The values are to be set from the application level. It is required
to allow config option PWM_DEADTIME in order to support dead time delay.
