msm: mdss: Prevent AD on WFD configuration
Assertive display is not allowed on HDMI and WFD configurations.
However, since WFD uses the writeback path, and AD uses the
writeback path for earlier hardware, then we must check which
hardware configuration is being used when checking writeback
panel configuration to prevent or allow AD.
