dt-bindings: iommu: riscv: Add bindings for Tenstorrent RISC-V IOMMU

Extend the binding to cover details specific to the Tenstorrent RISC-V
IOMMU. In particular, a second register range is added which contains
M-privileged registers, e.g., PMAs and PMPs.

The RISC-V spec S-privileged registers remain in the first register
range and are compatible with "riscv,iommu" so the Linux driver does not
notice any difference, but the binding will be used by OpenSBI and
potentially other M-mode software.
