[PATCH v2] dma: imx-sdma: clarify firmare not found warning

[s.hauer@pengutronix.de (Sascha Hauer)]

When a firmware cannot be found for the SDMA engine then we can
continue with the inernal ROM firmware.

The meaning of this message is frequently asked for, so make clear
that the driver still works with the internal ROM firmware and reduce
the loglevel from err to info.
