Mostafa Saleh d7cdf89c27 hw/arm/smmu-common: Add support for nested TLB 
This patch adds support for nested (combined) TLB entries.
The main function combine_tlb() is not used here but in the next
patches, but to simplify the patches it is introduced first.

Main changes:
1) New field added in the SMMUTLBEntry struct: parent_perm, for
   nested TLB, holds the stage-2 permission, this can be used to know
   the origin of a permission fault from a cached entry as caching
   the “and” of the permissions loses this information.

   SMMUPTWEventInfo is used to hold information about PTW faults so
   the event can be populated, the value of stage used to be set
   based on the current stage for TLB permission faults, however
   with the parent_perm, it is now set based on which perm has
   the missing permission

   When nesting is not enabled it has the same value as perm which
   doesn't change the logic.

2) As combined TLB implementation is used, the combination logic
   chooses:
   - tg and level from the entry which has the smallest addr_mask.
   - Based on that the iova that would be cached is recalculated.
   - Translated_addr is chosen from stage-2.
