virtmgr: adjust default swiotlb algorithm

This commit should be a no-op. The new algorithm gives the same answer
(14 MB) for a default microdroid VM config and the same or close or
other configs.

The new algorithm factors out of some of the predictable parts of
Linux's swiotlb usage. These will be the target of optimizations in
follow up commit.

Some parts take into account the page size now, but it is hardcoded to
4k because I haven't tested it with 16k mode yet.

Flag: NONE noop
Test: launch microdroid

Android Virtualization Framework (AVF)

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.
