[GFX-DISPLAY] Disable psb frame buffer driver ops to avoid intel logo disappear.

BZ: 38396

There is a black screen interval between firmware logo and Android
system logo, the logo drawn by firmware will be cleared intentionly
by kernel console layer, it is not what we want. Since frame buffer
operation won't be needed in Andriod system, disable driver layer's ops.
