pvmfw: Pre-populate pviommu nodes

This CL also add dtc parameter -@ to compile dtb file with pviommu
symbols. They would be used by assign device nodes.

However, -@ option also generates /__symbols__ for all symbols including
swiotlb, intc, and clk. But the list is limited so performance / size
impact would be insignificant.

Bug: 277993056
Test: fdtdump Check generated DTBO contains pviommu for followings: \
      - 10 pre-populated pviommu nodes with their own phandles.     \
      - /__symbols__ contains following properties:                 \
        - swiotlb = "/reserved-memory/restricted_dma_reserved";     \
        - intc = "/intc";                                           \
        - clk = "/pclk@3M";                                         \
        - pviommu_0 = "/pviommu0";                                  \
          ...                                                       \

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.
