     of/platform: Add common method to populate default bus

     The arch code calls of_platform_populate() with default match table
     when it wants to populate default bus.

     This patch introduce a new of_platform_default_populate_init() and 
make it
     arch_initcall_sync(it should be later than some iommu configration, eg,
     of_iommu_init() and swiotlb_late_init in arm64), then we can finish 
above
     job in common method.

     In order to avoid the default bus being populated twice, simply 
checking
     the flag of bus node whether has be set OF_POPULATED_BUS or not.

     After that, we can safely remove the caller in arch code.

     Btw, add debug print in of_platform_populate(), and use __func__ to
     print function's name of of_platform_bus_create().
