mmc: sdhci-of-esdhc: 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 the sdhci-of-esdhc driver to this allocation.
