iommu/arm-smmu: add .domain_{set,get}_attr for coherent walk control
Under certain conditions coherent hardware translation table walks can
result in degraded performance. Add a new domain attribute to
disable/enable this feature in generic code along with the domain
attribute setter and getter to handle it in the ARM SMMU driver.
