vmbase: Support secondary UARTs 0x2f8,0x3e8,0x2e8

Parameterize the code to allow printing to the "n-th" console and
setting up an arbitrary (up to MAX_CONSOLES) number of UARTs to be used
by client code.

Extend the layout to describe the 4 UARTs crosvm unconditionally
generates and configure console::init() to allow printing to any one of
them.

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.
