[PATCH] serial: exar: Add support for Sealevel 7xxxC serial cards

[Matthew Howell]

Add support for Sealevel 7xxxC serial cards.

Signed-off-by: Matthew Howell <matthew.howell@sealevel.com>

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.

Let me know if I need to make any changes.

This information needs to be above the signed-off-by line in the
changelog text.

Can you resend this as a v2 patch?

thanks,
