iommu/arm-smmu-v3: move stall_enabled to the cd table

A domain can be attached to multiple masters with different
master->stall_enabled values. The stall bit of a CD entry should follow
master->stall_enabled and has an inverse relationship with the
STE.S1STALLD bit.

The stall_enabled bit does not depend on any property of the domain, so
move it out of the arm_smmu_domain struct.  Move it to the CD table
struct so that it can fully describe how CD entries should be written to
it.
