Subject: [PATCH 1/2] drm: rcar-du: Refactor Feature and Quirk definitions

These flags are represented by bit fields. To make this clear, utilise
the BIT() macro.

This patch fails checkpatch's 80-char limit, due to the line comments
extending across the 80-char boundary on RCAR_DU_FEATURE_EXT_CTRL_REGS

To preserve formatting - this warning has been ignored.
