ata: sata_mv: check for errors when parsing nr-ports from dt If the nr-ports property is missing ata_host_alloc_pinfo is called with n_ports = 0. This results in host->ports[0] = NULL which later makes mv_init_host() oops when dereferencing this pointer. Instead be a bit more cooperative and fail the probing with an error message.
