mmc: sdhci_pltfm: Constify sdhci_pltfm_data
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.
