Despite that property name being generic, its content isn't and has been driver-specific which makes it hard to build any generic behaviour on top of it, both in kernel and user-space. Let's create a new bitmask tv norm property, that can contain any of the analog TV standards currently supported by kernel drivers. Each driver can then pass in a bitmask of the modes it supports. We'll then be able to phase out the older tv mode property.
