Subject: [PATCH 0/2] drm/etnaviv: Implement drm_gem_object_funcs::print_info()

It will be called by drm_gem_print_info() if have implemented, and this can
provide more information about the framebuffer objects. In order to make
the newly implemented etnaviv_gem_object_funcs::print_info() get in use,
we make the drm_gem_print_info() exported, then we re-implement the
etnaviv_gem_describe() base on it.

Sample Testing Information:

crtc-0	 DPI-2	    framebuffer  gpu		   mmu	 state

[root@...ora 0]# cat framebuffer
