serial: exar: Add support for Sealevel 7xxxC serial cards
commit 14ee78d5932afeb710c8305196a676a715bfdea8 upstream. Add support for Sealevel 7xxxC serial cards. This patch: * Adds IDs to recognize 7xxxC cards from Sealevel Systems. * Updates exar_pci_probe() to set nr_ports to last two bytes of primary dev ID for these cards.
