When DRM_RCAR_DU=y and DRM_RCAR_LVDS=m, there are several build errors
as reported by 'kernel test robot'. These can be corrected by changing
"imply" to "select".
In looking at this, the same problem (build errors) happens when
DRM_RCAR_DU=y and DRM_RCAR_CMM=m, so again change the "imply" to
"select" here as well.
These 2 changes fix the following 8 build/link errors:
