zx_status_t Create (ds::Bdf bdf, uint32_t domain_id, IommuImpl * parent, volatile ds::ExtendedContextEntry * context_entry, ktl::unique_ptr<DeviceContext> * device)Create a new DeviceContext representing the given BDF. It is a fatal error
to try to create a context for a BDF that already has one.

zx::result<uint64_t> SecondLevelMap (const fbl::RefPtr<VmObject> & vmo, uint64_t vmo_offset, size_t size, uint32_t perms)Use the second-level translation table to map the host pages in the given
range on |vmo| to the guest's address. Either maps the whole requested
range, returning the base dev_addr_t, or fails.

zx_status_t SecondLevelMapIdentity (paddr_t base, size_t size, uint32_t perms)Use the second-level translation table to identity-map the given range of
host pages.

void SecondLevelUnmapAllLocked ()Removes all mappings from the device context. This is only intended to be done just prior to
destruction as we need to perform unmapping whilst holding the parent lock.
