mmc: sdhci-pxav3: fix platform_data is not initialized 

pdev->dev.platform_data is not initialized if match is true in function
sdhci_pxav3_probe. Just local variable pdata is assigned the return value
from function pxav3_get_mmc_pdata().

static int sdhci_pxav3_probe(struct platform_device *pdev) {

    struct sdhci_pxa_platdata *pdata = pdev->dev.platform_data;
    ...
    if (match) {
		ret = mmc_of_parse(host->mmc);
		if (ret)
			goto err_of_parse;
		sdhci_get_of_property(pdev);
		pdata = pxav3_get_mmc_pdata(dev);
     }
     ...
}
