mmc: bcm2835_sdhci: Use calloc to allocate bcm2835_sdhci_host
We need to clear the allocated memory explicitly as the included struct sdhci_host has function pointers. Those are compared to NULL to test if this (optional) feature is supported. Leaving them undefined let u-boot jump to arbitrary memory. Signed-off-by: Alexander Stein <alexanders83@web.de>
