Instead of trying to match and probe platform and AMBA devices right
after each is registered, delay their probes until device_initcall_sync.

This means that devices will start probing once all built-in drivers
have registered, and after all platform and AMBA devices from the DT
have been registered already.

This allows us to prevent deferred probes by probing dependencies on
demand.

Changes in v4:
- Also defer probes of AMBA devices registered from the DT as they can
  also request resources.

This breaks arch/powerpc/sysdev/fsl_pci.c.  The PCI bus is an OF platform 
device, and it must be probed before pcibios_init() which is a 
subsys_initcall(), or else the PCI bus never gets scanned.
