mmc: sirf: fix sdhci_pltfm_init sequence
Patch "mmc: sdhci: Add size for caller in init+register" changed the interface for sdhci_pltfm_init, while patch "mmc: sdhci-sirf: add mmc host sdhci-pltfm based driver for SiRF SoCs" added a new driver with the old interface. This changes the sirf driver to use the new interface, avoiding one warning, and simplifying the init sequence. Since we're here already, this also adds an error path for failed clk_prepare_enable.
