iommu/riscv: Advertise Svpbmt support to generic page table
4087813 
The RISC-V IOMMU can optionally support Svpbmt page-based memory types
in its page table format. When present,the generic page table code can
use this capability to encode memory attributes (e.g. MMIO vs normal
memory) in PTEs.

iommupt: Encode IOMMU_MMIO/IOMMU_CACHE via RISC-V Svpbmt bits
db9160e 
When the RISC-V IOMMU page table format support Svpbmt, PBMT provides
a way to tag mappings with page-based memory types. Encode memory type
via PBMT in RISC-V IOMMU PTEs:

  - IOMMU_MMIO   -> PBMT=IO
  - !IOMMU_MMIO && !IOMMU_CACHE -> PBMT=NC
  - otherwise    -> PBMT=Normal (PBMT=0)

Only touch PBMT when PT_FEAT_RISCV_SVPBMT is advertised.
