The second solution adds some kind of complexity to rockbox code, which is
not always a good idea. Moreover, while it would be fine, it involves
hard-coding of other defines and so on.
The first idea is quite better, but still adds something that may be
avoided: why not simply keep the touchdev_disable and touchdev_wakeup? On
targets without touch power management the driver may simply discard events
by filtering. Also the latter isn't really the best option since it doesn't
reflect reality but, at least, doesn't add much complexity.
What do you think? Definitely I'm for the first option (or mine)
