Instead of device tree or other more standardized means, VMApple passes
platform configuration to the first stage boot loader in a binary encoded
format that resides at a dedicated RAM region in physical address space.
This patch models this configuration space as a qdev device which we can
then map at the fixed location in the address space. That way, we can
influence and annotate all configuration fields easily.
