mdss: mdp: secure buffer is unmaped without iommu attached
For secure content/buffers, it is a requirement that IOMMU is attached
before un-mapping can be called, otherwise the scm call to unmap the
buffer will not be successful. In the current implementation it is
possible to unmap buffer while going into suspend without IOMMU being
attached which leads to secure playback failures in subsequent sessions.
Fix this by ensuring IOMMU is attached before buffer is freed/unmapped.
