Jocelyn Falempe 3dd0be7a30 drm/ast: Handle framebuffer from dma-buf 
In the atomic update callback, ast should call
drm_gem_fb_begin_cpu_access() to make sure it can read the
framebuffer from the CPU, otherwise the data might not be there due
to cache, and synchronization.

Tested on a Lenovo SE100, while rendering on the ArrowLake GPU with
i915 driver, and using ast for display.
