The ast driver supports different transmitter chips to support DVI and HDMI connectors. It's al been packed into the same helpers functons and exported as VGA connector.
Introduce a separate set of connector helpers for each transmitter chip, and thus connector type. Also provide the correct encoder for each connector.
This change mostly affects the connector's get_modes helper, where VGA-, DVI- and HDMI-related code was lumped into the same function. It's now all separate. While at it, also rework and cleanup the initialization of the related data structures.
Tested on AST 2100 and AST 2300 hardware. I don't have hardware with special transmitter chips (SIL164, DP501), so I could only test the VGA code.
