ubifs: Remove ifdefs around CONFIG_UBIFS_ATIME_SUPPORT

Browse Source 
ifdefs reduce readability and compile coverage. This removes the ifdefs
around CONFIG_UBIFS_ATIME_SUPPORT by replacing them with IS_ENABLED()
where applicable. The fs layer would fall back to generic_update_time()
when .update_time doesn't exist. We do this fallback explicitly now.
