Attempts to build with CONFIG_ADF_MEMBLOCK=m result in the following
build error.
ERROR: "memblock_free" [drivers/video/adf/adf_memblock.ko] undefined!
memblock_free() is marked as __init_memblock, so exporting it seems to be
a bad idea. All other callers are only configurable into the kernel,
so do the same with ADF_MEMBLOCK.

If ADF is configured as module, each of the object files ends up being
a separate module. Since the functions are used across the various files
but not exported, this results in the observed build errors.
Modify the Makefile to create a single module instead.

The adf_device_post_nocopy function eventually calls the
dma_buf_attach and dma_buf_map_attachment functions. If the
dma_buf_attach function succeeds but the dma_buf_map_attachment
function fails, both the adf_buffer_map function and the
adf_device_post_nocopy function will call the dma_buf_detach
function to tear down the same dma-buf attachment.
