extend max buffer size for test.
just followed the error from drm.debug=0x5e and tried to force extend max buffer size returned by intel_fb_pitch_limit(), then 3 X 4K monitor works well then.
there are 2 commit b321803dfb and ac484963f9 touched this part, but not sure why it specify (8192 * cpp)? have some better way to extend the size ?
