Subject: [PATCH] ecore-drm2: Add API functions needed to port Ecore_Evas drm

This patch adds 2 new API functions which are required by Ecore_Evas
in order for it to function with drm. These API functions allow for
restricting pointer movement, and for setting the window id which will
be used when sending input events
