drm/ast: Initialized data needed to map fbdev memory
commit 28fb4cb7fa6f63dc2fbdb5f2564dcbead8e3eee0 upstream.
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.
