[SERIAL] SIIG 8-port serial boards support
This patch adds support for SIIG 8-port boards. These boards have 4 ports in separate bars and another 4 ports in the single bar. Because of this strange port arrangement these cards need special setup function. Fortunately no other SIIG cards have more than 4 port, so this setup function could be used for them too.
