serial: 8250_aspeed_vuart: initialize vuart->port in aspeed_vuart_probe()
Previously this had only been initialized if we hit the throttling path in aspeed_vuart_handle_irq(); moving it to the probe function is a slight consistency improvement and avoids redundant reinitialization in the interrupt handler. It also serves as preparation for converting the driver's I/O accesses to use port->port.membase instead of its own vuart->regs.
