pwm: sifive: Ensure the clk is enabled exactly once per running PWM
.apply() assumes the clk to be for a given PWM iff the PWM is enabled.
So make sure this is the case when .probe() completes. And in .remove()
disable the according number of times.
This fixes a clk enable/disable imbalance, if some PWMs are already running
at probe time.
Fixes: 9e37a53eb051 (pwm: sifive: Add a driver for SiFive SoC PWM)
