[PATCH 1/9] gma500: Initial support for our encoder and connector structs

[Alan Cox <alan@lxorguk.ukuu.org.uk>]

From: Patrik Jakobsson <patrik.r.jakobsson@gmail.com>

First step towards adding i915 alike encoder and connector abstractions. This
will make life easier when adding i915 output code into our driver. It also
removes the old psb_intel_output struct.
