mmc: sdhci-bcm-kona: Use sdhci_pltfm_unregister instead of open coded
This avoid duplicated implementation and also fixes missing iounmap() and release_mem_region() calls in sdhci_bcm_kona_remove(). sdhci_pltfm_init() calls request_mem_region() and ioremap(), thus we need to call the corresponding iounmap() and release_mem_region() calls in sdhci_bcm_kona_remove().
