Update mxs-dma driver to adopt generic DMA device tree binding. It
calls of_dma_controller_register() with mxs specific of_dma_xlate to
get the generic DMA device tree helper support. Then DMA clients only
need to call dma_request_slave_channel() for requesting a DMA channel
from dmaengine.
The existing way of requesting channel, clients directly call
dma_request_channel(), still work there, and will be removed after
all mxs-dma clients get converted to generic DMA device tree helper.

When the optional clk_ptp is absent, we can just set it to NULL, and
clk API will just handle it gracefully. It saves us from checking
clk_ptp whenever calling into clk API.
Also since clk_ptp is optional, the "ret" variable shouldn't be set
in case that the clock is absent.
