Subject: [PATCH v2 02/34] drm/drm_mode_object: increase max objects to accommodate new color props

DRM_OBJECT_MAX_PROPERTY limits the number of properties to be attached
and we are increasing that value all time we add a new property (generic
or driver-specific).

In this series, we are adding 13 new KMS driver-specific properties for
AMD color manage:
- CRTC Gamma enumerated Transfer Function
- Plane: Degamma LUT+size+TF, HDR multiplier, shaper LUT+size+TF, 3D
  LUT+size, blend LUT+size+TF (12)

Therefore, just increase DRM_OBJECT_MAX_PROPERTY to a number (64) that
accomodates these new properties and gives some room for others,
avoiding change this number everytime we add a new KMS property.
