copybit: Set default value on COPYBIT_TRANSFORM for Color layer.
1. For Color layer, set zero transform value on COPYBIT_TRANSFORM
otherwise it causes MDP IOMMU page fault at 90/270 degree rotation.
2. Color layer is part of Copybit context list, so no need to call
msm_copybit() explicitly for it, that will be called during flush.
