The sdhci_pltfm_data struct is never modified within the sdhci_pltfm module. So
make the pdata parameter to sdhci_pltfm_init and sdhci_pltfm_register const.
This allows drivers to declare their sdhci_pltfm_data struct as const.

This patch also makes the sdhci_pltfm_data declarations const where possible.

Commit 5ebf255 "mmc: sdhci-tegra: add basic support for Tegra114"
recently added sdhci_tegra114_pdata, which would need the same treatment.
