drm/connector: Rename legacy TV property

The current tv_mode has driver-specific values that don't allow to
easily share code using it, either at the userspace or kernel level.

Since we're going to introduce a new, generic, property that fit the
same purpose, let's rename this one to legacy_tv_mode to make it
obvious we should move away from it.
