[PATCH v4 11/13] mmc: sdhci-tegra: 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-tegra
to this allocation.
