Narendra Muppalla 43f4c3c9ce disp: msm: sde: create a dummy smmu device for scm transactions
Since drm smmu device is configured to support only 32 bit addressing,
but IOMMU expects 64 bit addressing configured device. This change
creates a dummy device with 64 bit mask for addressing to map and unmap the
shared memory for any scm call.
