iommu/arm-smmu-v3: Consolidate the STE generation for abort/bypass
This allows writing the flow of arm_smmu_write_strtab_ent() around abort and bypass domains more naturally. Note that the core code no longer supplies NULL domains, though there is still a flow in the driver that end up in arm_smmu_write_strtab_ent() with NULL. A later patch will remove it. Remove the duplicate calculation of the STE in arm_smmu_init_bypass_stes() and remove the force parameter. arm_smmu_rmr_install_bypass_ste() can now simply invoke arm_smmu_make_bypass_ste() directly. Rename arm_smmu_init_bypass_stes() to arm_smmu_init_initial_stes() to better reflect its purpose.
