Input: max8997_haptic - optimize PWM configuration

Both pwm_config() and pwm_enable() are wrappers around
pwm_apply_might_sleep(). Instead of calling this function twice only
call it once without an intermediate step.

Setup the PWM in max8997_haptic_enable() only where it was enabled
historically. max8997_haptic_set_duty_cycle() is renamed accordingly to
make it clear this function is only about the internal setup now.
pwm_config() was called earlier back then, but that call has no effect
on the hardware when the PWM is disabled, so delaying this configuration
doesn't make a difference.

As pwm_apply_might_sleep() is used now defining the whole state of the
PWM, the call to pwm_apply_args() in .probe() can be dropped now, too.
