serial: 8250_pxa: honor the port number from devicetree
Like the other OF-enabled drivers, use the port number from the firmware if the devicetree specifies an alias: aliases { ... serial2 = &uart2; /* Should be ttyS2 */ } This is how the deprecated pxa.c driver behaved, switching to 8250_pxa messes up the numbering.
