[PATCH 1/5] mmc: sdhci-esdhc-imx: add f_max field to private data

[Sascha Hauer]

The driver filled in the clk and clock fields in struct
sdhci_pltfm_host, but they are unused in the sdhci-pltfm
code and only ever used it for internal use. This adds
a field f_max to private data and uses it instead.
