24afc61990 powerpc/512x: Make pdm360ng_init() static
The mpc512x_defconfig config fails with:

  arch/powerpc/platforms/512x/pdm360ng.c:104:13: error: no previous prototype for ‘pdm360ng_init’ [-Werror=missing-prototypes]
  104 | void __init pdm360ng_init(void)
      |             ^~~~~~~~~~~~~

Fix it by making pdm360ng_init() static.

81d7cac4d1 powerpc: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

0aafbdf35c powerpc: Make generic_calibrate_decr() the default
ppc_md.calibrate_decr() is a mandatory item. Its nullity is never
checked so it must be non null on all platforms.

Most platforms define generic_calibrate_decr() as their
ppc_md.calibrate_decr(). Have time_init() call
generic_calibrate_decr() when ppc_md.calibrate_decr() is NULL,
and remove default assignment from all machines.

1c96fcdef8 powerpc/platforms: Use 'compatible' property for simple cases
Use the new 'compatible' property for simple cases.

checkpatch complains about the new compatible being undocumented
but in reality nothing is new so just ignore it for the time
being.

f2d576948d powerpc: Get rid of ppc_md.init_early()
It is now called right after platform probe, so the probe function
can just do the job.

5657138404 powerpc: Move 32-bit probe() machine to later in the boot process
This converts all the 32-bit platforms to use the expanded device-tree
which is a pretty mechanical change. Unlike 64-bit, the 32-bit kernel
didn't rely on platform initializations to setup the MMU since it
sets it up entirely before probe_machine() so the move has comparatively
less consequences though it's a bigger patch.

2abbbb63c9 powerpc/mpc512x: move common code to shared.c file
- implement all of the init, init early, and setup arch routines in the
  shared source file for the MPC512x PowerPC platform, and make all
  MPC512x based boards (ADS, PDM, generic) use those common routines
- remove declarations from header files for routines which aren't
  referenced from external callers any longer

this modification concentrates knowledge about the optional FSL DIU
support in one spot within the shared code, and makes all boards benefit
transparently from future improvements in the shared platform code

the change does not modify any behaviour but preserves all code paths
