vmbase: uart: Create abstraction layer over register write

This change creates an abstraction layer over register write accesses
(there are currently no read accesses) for 8250 UART driver. The direct
write volatile access have been replaced with a intermediate trait that
is accepted via newly introduced generic to `Uart`.

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.
