In preparation for adding stage-2 support, add a S2 config
struct(SMMUS2Cfg), composed of the following fields and embedded in
the main SMMUTransCfg:
-tsz: Input range
-sl0: start level of translation
-affd: AF fault disable
-granule_sz: Granule page shift
-vmid: VMID
-vttb: PA of translation table
-oas: Output address size
They will be used in the next patches in stage-2 address translation.
No functional change intended.
