   ## Summary
   PWM drivers usually supports dead time generators that automatically insert 
output activation delay for complementary PWM outputs. This is useful for some 
control purposes as control of H bridge for example.
   
   The first commit adds an application to driver interface that can be used to 
set up those delays (if supported by the selected architecture) directly from 
the application. The set up remains the same as for duty cycle value.
   
   The second commit adds dead time delay support for SAMv7 MCU.
   
   ## Impact
   
   SAMv7 and generic PWM driver (dead time remains under by default disabled 
configuration option and therefore should not have any impact on current state 
of the driver or already implemented applications).
   
   ## Testing
   
   Tested on same70-xplained board.
