The custom init call may need more data to perform its job, so we pass it a pointer to pdata, too. Also, always use the platform_id specific data even if platform_data is present. Doing that, platform_data can additionally be parsed by init() for board-specific information (via sdhci->mmc->parent). (Note: the old behaviour was that you could override the platform_id specific data with your own. However, one can still do this by using the "sdhci" id instead of "sdhci-<something>".)
