Subject: [PATCH 1/5] drivers/mmc/host: constify sdhci_pltfm_data structures

The sdhci_pltfm_data structure is only passed as the second argument
of sdhci_pltfm_init, which is const, so the sdhci_pltfm_data structure can
be const as well.

Done with the help of Coccinelle.

Signed-off-by: Julia Lawall <Julia.Lawall@...6.fr>
