iommu/arm-smmu-qcom: Select identity domain for sc8280xp MDSS 



The Qualcomm display driver installs a translation domain once it has
mapped a framebuffer. Use the identity domain for this device on
SC8280XP as well, to avoid faults from EFI FB accessing the framebuffer
while this is being set up.
