Add several ways to restrict UART probing when matching devices: - max port count, - PCI subsystem ID mask (some cards encode the port count there), - Base Address Register mask (some cards only have UART in the first 2 ranges). Use those to match 2 specific NetMos chips, and avoid screwing up when input_server tries to access UARTs at boggus ranges. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35965 a95241bf-73f2-0310-859d-f6bbb57e9c96
