button: allow disabling software poweroff

Browse source 
On some devices, the button driver allows a "software poweroff" by long-
pressing a certain key. This behavior is inconvnient when that button needs
to be held down for other purposes, such as moving the cursor in rockpaint
or sgt-untangle.

This patch allows selectively disabling the software poweroff (enabled by
default) from both core and plugin code.
