[PATCH 14/19] powerpc: mpc83xx: Switch to of_platform_populate

[J. Neuschäfer via B4 Relay]

From: "J. Neuschäfer" <j.ne at posteo.net>

Quoting from drivers/of/platform.c:

> of_platform_populate() - [...]
> Similar to of_platform_bus_probe(), this function walks the device
> tree and creates devices from nodes.  It differs in that it follows
> the modern convention of requiring all device nodes to have a
> 'compatible' property, and it is suitable for creating devices which
> are children of the root node (of_platform_bus_probe will only create
> children of the root which are selected by the @matches argument).

This is useful for new board ports because it means that the C code does
not have to anticipate every node that is placed directly under the root.

As a consequence, the of_bus_ids list can be much shorter, and I've
trimmed it to the necessary parts:

 - device-type = "soc" and compatible = "simple-bus" for the SoC bus
 - compatible = "gianfar" for the Ethernet controller (TSEC), which
   may contain an MDIO bus, which needs to be probed, as a subnode
