[PATCH 1/4] serial: vt8500: Find console ports in the serial core state

[Alexey Charkov <alchark@gmail.com>]

Look up the console's port in vt8500_uart_driver.state[], which the
serial core fills before it registers the console, and drop the private
vt8500_uart_ports[] array that only mirrors it and gets in the way.
