hw/arm/smmuv3: Update translation config to hold stage-2
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: Size of IPA input region (S2T0SZ)
-sl0: Start level of translation (S2SL0)
-affd: AF Fault Disable (S2AFFD)
-record_faults: Record fault events (S2R)
-granule_sz: Granule page shift (based on S2TG)
-vmid: Virtual Machine ID (S2VMID)
-vttb: Address of translation table base (S2TTB)
-eff_ps: Effective PA output range (based on S2PS)
They will be used in the next patches in stage-2 address translation.
The fields in SMMUS2Cfg, are reordered to make the shared and stage-1
fields next to each other, this reordering didn't change the struct
size (104 bytes before and after).
Stage-1 only fields: aa64, asid, tt, ttb, tbi, record_faults, oas.
oas is stage-1 output address size. However, it is used to check
input address in case stage-1 is unimplemented or bypassed according
to SMMUv3 manual IHI0070.E "3.4. Address sizes"
Shared fields: stage, disabled, bypassed, aborted, iotlb_*.
No functional change intended.
