drm/komeda: Add image enhancement support
Besides scaling, Arm display scaler also can support image enhancement.
For support it, Add a new property "img_enhancement" to plane, then user
can turn on/off it by this property, and kernel follow user's requirement
to maitain the state and enable/disable the real HW image enhancement.
v2: Rebase and rename "needs_img_enhancement" to "en_img_enhancement"
