[PATCH 1/2] mmc: sdhci-bcm-kona: Use sdhci_pltfm_unregister instead of open coded

[Axel Lin <axel.lin@ingics.com>]

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().
