mmc: sdhci-iproc: Use sdhci_pltfm_remove()

Use sdhci_pltfm_remove() instead of sdhci_pltfm_unregister() so that
devm_clk_get_enabled() can be used for pltfm_host->clk.

This has the side effect that the order of operations on the error path
and remove path is not the same as it was before, but should be safe
nevertheless.
