This series is part of a bigger series exploring data-driven machine creation
using device tree blobs on top of the e500 machines [1]. It contains patches to
make this exploration easier which are also expected to provide value in
themselves.

The cleanup starts with the e500 machine class itself, then proceeds with
machine-specific device models and concludes with more or less loosely related
devices. Device cleanup mostly consists of using the DEFINE_TYPES() macro.

v3:
* Pick up R-B tags (Kevin, Zoltan -- thanks!)
* Rely on trace events only and drop unimp logging in CCSR space after
  discussion
* Merge https://patchew.org/QEMU/20241005100228.28094-1-shentey@gmail.com/ since
  ARM now mostly unaffected
* Add patch to reuse MII constants in etsec device

Testing done:
* Build qemu_ppc64_e5500_defconfig in Buildroot, run it in the ppce500 machine
  and issue the `poweroff` command. Observe that QEMU is shut down cleanly.

v2:
* Add R-b tags (Cedric, Zoltan -- thanks!)
* Add missing S-o-b tag to ds1338 patch (Cedric)
* Populate POR PLL ratio status register with real-world values (Zoltan)
* Rephrase one commit message (Zoltan)
* Also rename header of ppce500_ccsr to match struct name
* Don't mention ppc440_bamboo in license since unrelated (Zoltan)
* Various style changes (Zoltan)
