This commit provides similar cleanups as commit 83eacdfa2529 ("mmc: sdhci: disable the clock in sdhci_pltfm_unregister()") did for unregister hooks. Some drivers duplicate code to handle pltfm_host->clk in their own hooks. The clock can be handled in sdhci_pltfm.c so that drivers can reuse sdhci_pltfm_pmops.
