The PXA PWM binding is the only one that doesn't pass the PWM line index
as first parameter of the parameter cells. However this can be upgraded
to the mandatory binding for all new PWM drivers without breaking
compatibility for old device trees using #pwm-cells = <1>.
So bump #pwm-cells to 3 with the (undocumented) promise to keep the old
behaviour for #pwm-cells = <1>.
