Declare etnaviv_iommu_ops structure as const as it is only used when
the reference of one of its field is stored in the ops field of a
iommu_domain structure. This ops field is of type const, so
etnaviv_iommu_ops structures having similar properties can be declared
const too.
Done using Coccinelle:

Before and after size details of .o file remains the same after
cross compiling for arm architecture.
