This series of patches add Freescale ASRC module driver support along
with the extra request in imx-sdma structure required by SDMA Device
to Device script.

The previous version has been in the maillist for nearly six months
without any comment and reply. So I decide to drop the SDMA part's
change since this series focus on ASRC support (Later, we can send
SDMA part separately.) so that ASRC driver may get upstream first.

v6: (Follows Mark Rutland's comments)
 * PATCH-2: Revised the big endian part in the binding document.
v5: (All follow Varka's suggestions)
 * PATCH-2: Added missing '\n' to pair_err() calls.
 * PATCH-2: Return the final regmap_write() for fsl_asrc_init().
 * PATCH-2: Dropped fsl_asrc_devtype and use simple ids behind fsl_asrc_pm.
 * PATCH-2: Use of_device_is_compatible() to differ compatible directly.
 * PATCH-2: Fixed indentation for devm_regmap_init_mmio_clk() call.
v4: (All follow Varka's suggestions)
 * PATCH-2: Added '\n' to dev_dbg() inside fsl_asrc_isr().
 * PATCH-2: Added indentations to DT binding document.
 * PATCH-2: Redefined fsl_asrc_set_watermarks() as void type.
 * PATCH-2: Put fsl_asrc_isr() and fsl_asrc_ids before probe()
 * PATCH-1: Added an Acked-by from Shawn Guo
 * PATCH-2: Dropped THIS_MODULE as Tobias suggests
 * PATCH-2: Use dma_coerce_mask_and_coherent() in fsl_asrc_dma_pcm_new()
 * PATCH-2: Added substream check in fsl_asrc_dma_pcm_new()
 * PATCH-1: Dropped the change to SDMA driver.
 * PATCH-2: Dropped useless member in private data structures.
 * PATCH-2: Refined some comments in fsl_asrc_dma.c driver.
 * PATCH-2: Refined commit comments.
