Subject: [RFC PATCH 23/30] of/platform: Export of_platform_device_create_pdata()

Export of_platform_device_create_pdata() to be used by drivers to
create child devices with the given platform data. This can be used
by platform specific driver to send platform data core driver. For e.g.,
this will be used by TI's J721E SoC specific PCIe driver to send
->start_link() ops and ->is_link_up() ops to Cadence core PCIe driver.
