iommu_map_sg has been updated and is expecting argument

This change adds smmu devices as separate devices and display
driver waits for these devices to bound before using any smmu
operation. This fixes recent stability issues where devices
were not probed during the dpu hw initialization.

During secure video to secure ui transition, since
secure ui requires s2 direct translation, display driver
will detach the iommu device after unmap of the buffers
attached to the CB.
In this regard, upstream framework which can independently
request for buffer free to unmap on the buffer creates an
illegal state where in dma ops are attached and iommu device
is dettached.
Cache the dma ops before detaching the CB and set it to
NULL during iommu device detach, to avoid multiple unmap
calls on the buffer.

1.Typecast to avoid distinct pointer type comparison
2.Keep DMA mask aligned with api definition.
3.Add Suffix for literals
4.Remove multfrac func to avoid uncompatible division.
5.64-bit division( operator "/") on 32-bit platforms is not supported.
Using platform independent API's here
