The DLL(Delay Line) is newly added to assist in sampling read data.
The DLL provides the ability to programmatically select a quantized
delay (in fractions of the clock period) regardless of on-chip variations
such as process, voltage and temperature (PVT).

This patch adds a user interface to set slave delay line via device tree.
It's usually used in high speed mode like mmc DDR mode when the signal
quality is not good caused by board design, e.g. the signal path is too
long.  User can manually set delay line to find a suitable data sampling
window for card to work properly.

Without proper pinctrl state, the card may not be able to work
on high speed stablely. e.g. SDR104.

This patch add pinctrl state switch code according to different
uhs mode include 100mhz sate, 200mhz sate and normal state
(50Mhz and below).

There's a missing script for hdmi audio support in current sdma driver,
thus add it.

This HDMI script doesn't use bd to copy memory like a normal one does
but only to update the memory address for HDMI internal AHB DMA and
then trigger its procedure automatically.

For the sake of support asrc p2p, the sdma driver need to be updated.

1. Add another dma_request, p2p need two dma_request.
2. There are some cases which need to change the config after the
dma_request_channel. add dma_request config in dmaengine_slave_config().
3. add dma_request0 and dma_request1 in dma_slave_config for runtime config
in dmaengine_slave_config.

It's ported from v3.5.7, which contains ePxP DMAENGINE driver and
a client driver named pxp_device. This patch also includes the changes:
- use uapi header file
- remove VM_RESERVED since it's deprecated, and drop redundant VM_IO flag
  since it's automatically set in remap_pfn_range()
- use <linux/platform_data/dma-imx.h> instead of <mach/dma.h>
- use devm_kzalloc() instead in pxp_probe()
- use macro __KERNEL__ in pxp_dma uapi header to avoid definition conflict

To support SSI dual-fifo mode, we need to add dual-fifo script for sdma.
