drm/ast: Initialized data needed to map fbdev memory
Due to a missing initialization there was no way to map fbdev memory. Thus for example using the Xserver with the fbdev driver failed. This fix adds initialization for fix.smem_start and fix.smem_len in the fb_info structure, which fixes this problem.
