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.

The mx6sl supports standard sdhci tuning, then esdhc_executing_tuning
is only needed for mx6q/dl. We introduce is_imx6_usdhc() and
is_imx6sl_usdhc() to handle the difference.

The standard tuning is enabled by setting ESDHC_TUNE_CTRL_STD_TUNING_EN bit
in new register ESDHC_TUNE_CTRL and operates with new tuning bits
defined in SDHCI_ACMD12_ERR register.

Note: mx6sl can also work on the old manually tuning mode as mx6q/dl if
not enable standard tuning mode.

Create a struct esdhc_soc_data with moving 'flags' field from
pltfm_imx_data into it, and pass the pointer of this SoC specific data
structure through of_device_id.data directly, so that the translation
from enum imx_esdhc_type to flags can be saved.

With the change, enum imx_esdhc_type can be eliminated, since we can
implement the is_imx*_esdhc() by checking the esdhc_soc_data pointer.
The unused is_imx35_esdhc() and is_imx51_esdhc() are also removed, and the
others are kept there as we will need to use them to handle some small
register differences later, where use of new flags might be a little
overkilled.
