Subject: [PATCH] drm: rcar-du: Fix build error

On arm{32,64} allyesconfig builds:

drivers/gpu/drm/rcar-du/rcar_dw_hdmi.c:40:1: error: incomplete result type 'enum drm_mode_status' in function definition
drivers/gpu/drm/rcar-du/rcar_dw_hdmi.c:47:10: error: incomplete definition of type 'struct drm_display_mode'
drivers/gpu/drm/rcar-du/rcar_dw_hdmi.c:48:10: error: use of undeclared identifier 'MODE_CLOCK_HIGH'
drivers/gpu/drm/rcar-du/rcar_dw_hdmi.c:50:9: error: use of undeclared identifier 'MODE_OK'

After the removal of drmP.h from this file and its removal from
bridge/dw_hdmi.h, these types are not defined anymore, as they
were implicitly coming into that file through drm_crtc.h.

Fixes: 428747ae5cca ("drm: remove include of drmP.h from bridge/dw_hdmi.h")
Fixes: 9a47db8e7a9d ("drm: rcar-du: Remove inclusion of drmP.h")
