On WFD/HDMI connection, if the configured resolution is less than Primary Resolution, Display HAL does the following: 1. sends hpd notification to SF with primary resolution. 2. configures MDP pipes with configured Resolution. This is done to improve UI quality as MDP has better downscale filter options compared to GPU. This works only for QCOM WFD proprietary solution. Change-Id: Ic20e837bf02c0f7b6718946e70b936f3a469fa7c
