[PATCH v2 1/4] dt-bindings: misc: qcom,fastrpc: add iommu-ranges support for context bank

[Vinayak Katoch <vinayak.katoch@oss.qualcomm.com>]

The driver uses the presence of iommu-ranges on a context bank node to
identify it as dedicated for extended IOVA mapping. iommu-ranges lists
the IOVA ranges the IOMMU allocator may use for that device; any range
not listed is left unused.

Add iommu-ranges to the compute-cb subnode properties so the DT
validator accepts it on context bank nodes.

Relax #address-cells to enum: [1, 2] and #size-cells to enum: [0, 2] to
allow platforms that require 64-bit values in iommu-ranges to pass
binding validation.
