I'm not sure if this is such a good idea, not all jz4740 based board
necessarily require PWM.

This really only restores previous behaviour. But I agree that this is
potentially not what we want. Maybe we should just not select this for
any boards but rather leave it up to some default configuration. If so
the patch can be made simpler by just removing the HAVE_PWM entries.

At least for JZ4740 I think that is the better solution.

Okay, I'll give other people the chance to comment on this. Especially
for PXA there are many boards that use the PWM for backlight and it
would be interesting to hear from them how they want this to be handled.
