From e3dca5eb510aa12130188f1c49e214fe575a0840 Mon Sep 17 00:00:00 2001

Subject: drm/rcar-du: Rename platform data fields to match what they describe

The struct rcar_du_encoder_data encoder::field describes the encoder
type, and the rcar_du_encoder_lvds_data and rcar_du_encoder_vga_data
structures describe connector properties. Rename them accordingly.
