Series pwm: Make pwmchip_remove return void | expand

The driver is supposed to stay functional until pwmchip_remove()
returns. So disable clocks only after that.

pwmchip_remove() always returns 0, so the return code can be ignored
which keeps ehrpwm_pwm_remove() a bit simpler and eventually allows to
make pwmchip_remove() return void.
