sdm: Fix refresh seqeunce for QDCM solid fill color

Browse Source 
Calibration tool issues binder call to display solid fill color onto
screen for calibration. Acquire scope lock to ensure that there is no
race condition between binder thread and display thread w.r.t solid fill
color. Block the solid fill binder call with a delay to ensure that
solid fill color is displayed.
