exynos_mmc_init() always returns zero, so for the caller it looks like it never fails.
Correct this by returning the error code of process_nodes(). For process_nodes() do something similar and return early when do_sdhci_init() fails.
v2: Only fail in process_nodes() if we fail on all available nodes.
