[PATCH 4/13] devres: implement managed DMA interface

Implement managed DMA interface - dmam_alloc_coherent(), dmam_free_coherent(), dmam_declare_coherent_memory(), dmam_pool_create() and dmam_pool_destroy(). Except for being managed, these take the same arguments and have the same effect as non-managed counterparts. Signed-off-by: Tejun Heo
