of/device: Merge of_platform_bus_probe()

Browse Source 
Merge common code between PowerPC and microblaze.  This patch merges
the code that scans the tree and registers devices.  The functions
merged are of_platform_bus_probe(), of_platform_bus_create(), and
of_platform_device_create().

This patch also move the of_default_bus_ids[] table out of a Microblaze
header file and makes it non-static.  The device ids table isn't merged
because powerpc and microblaze use different default data.
