atmel_pwm: set up only one PWM clock when allocating a clock

This patch will only setup one clock, if free, and return this clock to the
caller.  The previous solution would setup both clocks with the same prescaler
and divider and return PWM_CPR_CLKB, thus taking both clocks in the same call
without the caller knowing.
