[PATCH 07/26] OF platform: export of_amba_device_create()

[Davide Ciminaghi <ciminaghi@gnudd.com>]

This is needed because the pci-amba bus will create one or more amba devices
for each probed pci device. We cannot create all the devices belonging to
the same amba bus with just one call to of_platform_populate()
