Missing dependency: `device-tree-compiler`

[kaddkaka]

I'm following the installation guide, but there seems to be dependencies missing form the instructions.

The step apt-get install device-tree-compiler as mentioned at https://github.com/riscv/riscv-isa-sim#build-steps is missing.

Also, I couldn't not build spike with clang12 (got warnings in boost source code). But building with gcc worked fine.

Example error from clang build:

I have pushed a fix for the docs on this branch. Will be merging soon.

Regarding spike with clang build, I guess that is a question best posted at the riscv-isa-sim repository.

new docs fix this.. hence closing this.
