This is not really how of_platform_bus_probe was meant to be used.
Instead of listing the device you want to probe, you should list
all buses that potentially contain a device that you are probing.
Normally, an ata controller is not a top-level device but instead
the child of an SOC bus device, and then you just probe all
SOC devices, which means their children get added to the device
tree.
In your case, that would probably mean that you have to another
entry in the "ranges" of the soc8349 node, or add a second socXXXX
node that has the 0xf0000000 ranges, depending on the actual layout
of the SOC.
