powerpc/85xx: don't call of_platform_bus_probe() twice
Commit 46d026ac ("powerpc/85xx: consolidate of_platform_bus_probe calls") replaced platform-specific of_device_id tables with a single function that probes the most of the busses in 85xx device trees. If a specific platform needed additional busses probed, then it could call of_platform_bus_probe() again. Typically, the additional platform-specific busses are children of existing busses that have already been probed. of_platform_bus_probe() does not handle those child busses automatically. Unfortunately, this doesn't actually work. The second (platform-specific) call to of_platform_bus_probe() never finds any of the busses it's asked to find. To remedy this, the platform-specific of_device_id tables are eliminated, and their entries are merged into mpc85xx_common_ids[], so that all busses are probed at once.
