[PATCH 1/2] hmi-controller: fix wrong background surface size

[Ucan, Emre (ADITG/SW1)]

In current implementation, the size of the first application
layer is used for the background image of a display.

This is wrong because:
	1. The background surface should be fullscreen.
	2. Each display could have different resolution.

We should use the size of the base layer of each display
for the background image.
