This fixes a bunch of bugs I ran into while reworking how qdevs plug
into buses.

I instrumented the code a bit to flush out instances of bug patterns.
I posted these hacks separately as '[PATCH not-for-merge 0/5]
Instrumentation for "Fixes around device realization"'.  PATCH 2/5
since became "[PATCH 0/2] qom: Make "info qom-tree" show children
sorted".  It should be applied first.

v3:
* PATCH 09: Handle errors even though they're impossible [Peter]
  Commit message typo
* PATCH 19: Rebase onto commit 26cd0362dd4 (machines spike_v1.9.1 and
  spike_v1.10 are gone) and commit fe0fe4735e7 (new machine opentitan)

v2:
* Rebased
* PATCH 01: Also fix MMIO addresses, with Alistair's help
* PATCH 04+05: Replaced by better patches from Cédric
* PATCH 01-03+06+08-11+18: Commit messages improved [Peter, Paolo]
* PATCH 08+09+18: Avoid qdev_init_nofail() [Peter]
* PATCH 22: Assertion simplified
