5c3ef39738f74a3759918cc1a1ad099504f9d1b7 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.
