[PATCH v3 2/3] drm/sti: Remove local fbdev emulation Kconfig option

[Vincent ABRIOU]

Hi Archit,

I tested fbdev_emulation module param and it works fine for the sti driver.
I will abandon my patch and integrate yours. And if you don't mind, I 
will update your patch to remove the #ifdef CONFIG_DRM_FBDEV_EMULATION.

Thanks
Vincent
