When Dynamic Resolution Change (DRC) is triggered in the WiFi display
stack, it results in a PAUSE and a RESUME event. During DRC, the
dimensions of the framebuffer are changed. To support DRC we need to:
1. Check if a RESUME event is the result of a valid DRC event
2. Reconfigure the display's attributes to reflect resolution change
3. Enable MDP downscaling when necessary (Valid DRC cases)

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.
