vmbase: Support missing SwiotlbInfo DT node
Stop failing with an Err() when SwiotlbInfo::new_from_fdt() is called on
DTs missing the "restricted-dma-pool" (e.g. in non-protected VMs) and
instead return Ok(None), which the caller can handle appropriately.
While here, use the proper error code (BadValue) when a <reg> property
is present but empty or is missing a size.

Android Virtualization Framework (AVF) provides secure and private execution environments for executing code. AVF is ideal for security-oriented use cases that require stronger isolation assurances over those offered by Android’s app sandbox.
Visit our public doc site to learn more about what AVF is, what it is for, and how it is structured. This repository contains source code for userspace components of AVF.
If you want a quick start, see the getting started guideline and follow the steps there.
