[PATCH v4 01/13] mmc: sdhci-bcm2835: use sdhci_pltfm_init for private allocation

Commit 0e748234293f ("mmc: sdhci: Add size for caller in init+register")
allows users of sdhci_pltfm to allocate private space in calls to
sdhci_pltfm_init+sdhci_pltfm_register. This patch migrates sdhci-bcm2835
to this allocation.
