6d9bc7fa8f pmgr: Unify defs with Linux, clean up device relationships. 
This enables parent devices that are required by active child devices,
because iBoot leaves behind some broken dependencies.

72788291e6 memory: Map all RAM to the top, minus carveouts 
This unbreaks dcp.py and other things that need to access reserved
regions. This way we don't have to start doing manual MMU maps, but
we're still safe from SErrors caused by hitting TZ carveouts.

da024ffbd8 memory: Only map available RAM 
We saw some crazy speculation running in the HV breaking things by
reading from invalid RAM, so let's actually map only what's available.
For now we do map all lowmem as we haven't seen SErrors there yet, but
we stop at the high boundary.

Fixes: #97

the radios. Running this before booting Linux will make the network
