[PATCH v2] mmc: mxs-mmc: Remove platform data

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <fabio.estevam@freescale.com>

All MXS users have been converted to device tree and the board files have been
removed.

No need to keep platform data in the driver.

Also move bus_width declaration in the beggining of mxs_mmc_probe() to avoid:
'warning: ISO C90 forbids mixed declarations and code'.

Changes since v1:
- Also remove mxs_mmc_platform_data and linux/mmc/mxs-mmc.h, which was used only
to include mxs_mmc_platform_data definition.
