Subject[PATCH 4/4] drm/msm: Fix default fb var width and height
The framebuffer var width and height should reflect the size of
framebuffer memory allocated, which is the entire surface size.

In case of dual DSI connectors with TILE properties, this change
makes the whole image show on the dual DSI panel, instead of
duplicated images on both sides.
