Lukas Wunner 64a05aadf9 serial: pl011: Don't leak amba_ports entry on driver register error 
commit 89efbe70b2 upstream.

pl011_probe() calls pl011_setup_port() to reserve an amba_ports[] entry,
then calls pl011_register_port() to register the uart driver with the
tty layer.

If registration of the uart driver fails, the amba_ports[] entry is not
released.  If this happens 14 times (value of UART_NR macro), then all
amba_ports[] entries will have been leaked and driver probing is no
longer possible.  (To be fair, that can only happen if the DeviceTree
doesn't contain alias IDs since they cause the same entry to be used for
a given port.)   Fix it.

Fixes: ef2889f7ff ("serial: pl011: Move uart_register_driver call to device")
