serial: mxs-auart: Remove irq from private structure
The irq number is only used inside the probe function, so there is no need
to keep it in the private mxs_auart_port structure.
Use a local 'irq' variable for storing the irq number instead.
Also make its type of 'int' as platform_get_irq() may fail and return a
negative number.
