Almost all users of cpu->cfg.satp_mode care about the "max" value
satp_mode_max_from_map(cpu->cfg.satp_mode.map). Convert the QOM
properties back into it. For TCG, deduce the bitmap of supported modes
from valid_vm[].

Do not create the RHCT MMU type entry for RV32 CPUs, since it
only has definitions for SV39/SV48/SV57. Likewise, check that
satp_mode_max_from_map() will actually return a valid value, skipping
the MMU type entry if all MMU types were disabled on the command line.

RISC-V IO Mapping Table (RIMT) is a new static ACPI table used to
communicate IOMMU information to the OS. Add support for creating this
table when the IOMMU is present. The specification is frozen and
available at [1].
