[PATCH] mci: imx-esdhc: retire esdhc_platform_data

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

We have no board in-tree that doesn't probe the imx-esdhc from DT.
The platform data is thus unused as the PBL usage happens without it,
therefore remove that struct definition and the dead code handling it.
