altos: Get stm32l pwm driver working
Fix the CCMR1_OC1PE and CCMR2_OC3PE values.
Disable clock when no PWM outputs are running.
Fix the apb1enr value for the timer.
Set ARR value to PWM_MAX - 1 -- ARR is off by one.
Sets the GPIO pins to 40MHz bandwidth for sharper edges.
Tested on EasyMega, but that code is not included as it breaks the
companion protocol.
