mmc: sdhci-sprd: Fix some resource leaks in the remove function
[ Upstream commit c9c256a8b0dc09c305c409d6264cc016af2ba38d ]
'sdhci_remove_host()' and 'sdhci_pltfm_free()' should be used in place of
'mmc_remove_host()' and 'mmc_free_host()'.
This avoids some resource leaks, is more in line with the error handling
path of the probe function, and is more consistent with other drivers.
