V4L/DVB (9231): cx23885: Define num_frontends as a function of the port
This allows some cardcoded functions to be more flexible, and paves the way for any future cards that may have MFE support. Better to add it now when the MFE patches is fresh in peoples mind, rather than 12 months from now when new cards appear.
