[RFC PATCH v2 02/11] hw/arm/smmuv3: Update translation config to hold stage-2

[Mostafa Saleh <smostafa@google.com>]

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.
