drm/rockchip: Embed drm_encoder into rockchip_decoder
The VOP2 driver needs rockchip specific information for a drm_encoder.
This patch creates a struct rockchip_encoder with a struct drm_encoder
embedded in it. This is used throughout the rockchip driver instead of
struct drm_encoder directly.
The information the VOP2 drivers needs is the of_graph endpoint node
of the encoder. To ease bisectability this is added here.
While at it convert the different encoder-to-driverdata macros to
static inline functions in order to gain type safety and readability.
