drm/ast: Use managed MM initialization
Cleaning up ast's MM code with ast_mm_fini() resets the write-combine
flags on the VRAM I/O memory. Drop ast_mm_fini() in favor of an auto-
release callback. Releasing the device also executes the callback.

drm/ast: Move VRAM size detection to ast_mm.c
VRAM size detection is only relevant to the memory management. Move
the code into ast_mm.c.
While at it, rename the function to ast_get_vram_size(). The function
argument's type is now struct ast_private. The result is stored in a
local variable and not in struct ast_private any longer.

drm/ast: Rename ast_ttm.c to ast_mm.c
Although built upon TTM, the ast driver's VRAM MM helper does not
expose TTM to its users. Rename the related ast file to ast_mm.c.
