[PATCH v2] iommu/arm-smmu-qcom: Add SM8450 MDSS compatible

[Esteban Urrutia via B4 Relay]

From: Esteban Urrutia <esteuwu@xxxxxxxxx>

Add the compatible for the MDSS client on the Snapdragon 8 Gen 1 so it can
be properly configured by the IOMMU driver.

Otherwise, there is an unhandled context fault, because the framebuffer is
already configured in UEFI.
