lpass ports numbers have been added but the afe/apm driver never got updated with new max port value that it uses to store dai specific data. There are more than one places these values are cached and always become out of sync. This will result in array out of bounds and weird driver behaviour. To catch such issues, first add a single place where we can define max port and second add a check in common parsing code which can error out before corrupting the memory with out of bounds array access. This should help both avoid and catch these type of mistakes in future.
