[ Upstream commit c90876a695dd83e76680b88b40067275a5982811 ]
In preparation for adding support for MT8195's HDMI reserved DPI instance, move the input_2p_en bit for DP_INTF to platform data.
While at it, remove the input_2pixel member from platform data as having this bit implies that the 2pixel feature must be enabled.
