Support Driver Model for fsl esdhc driver.
- Introduce a new structure struct fsl_esdhc_priv
- Refactor fsl_esdhc_initialize which is originally used by board code.
- Introduce fsl_esdhc_init to be common usage for DM and non-DM
- Introduce fsl_esdhc_cfg_to_priv to build the bridge for non-DM part.
- The original API for board code is still there, but we use 'fsl_esdhc_cfg_to_priv' and 'fsl_esdhc_init' to serve it.
- All the functions are changed to use 'struct fsl_esdhc_priv', except fsl_esdhc_initialize.
- Since clk driver is not implemented, use mxc_get_clock to geth the clk and fill 'priv->sdhc_clk'.
Has been tested on i.MX6UL 14X14 EVK board: " =>dm tree .... simple_bus [ + ] | `-- aips-bus@02100000 mmc [ + ] | |-- usdhc@02190000 mmc [ + ] | |-- usdhc@02194000 .... => mmc list FSL_SDHC: 0 (SD) FSL_SDHC: 1 (SD) "
After pulling in device tree files from the mainline kernel, I was able to test this on a SABRE Lite, so you can add my:

Thanks, Eric.
Thank you for adding this support.
Is somebody prepping patches to pull in support for i.MX6DQ?
I can not follow you on this? you mean adding dts files for i.MX6DQ or else?
Yes, or at least the .dtsi and .h files from arch/arm/boot/dts/.
Your i.MX6UL patch pulled in the files needed for UL, and the same is needed for i.MX6DQ, i.MX6SX and such.
I have a patch pulling i.MX6DQ files from linux-stable (4.4), but
That's great.
don't want to jump in the middle if somebody else is doing this.
I have not began this. If you have patches, feel free to post them out:)
Thanks, Peng.

Eric
