of: partition: implement of_partition_ensure_probed
The device tree nodes for both barebox environment and state can have
phandles that reference partitions. Environment runs at late_initcall
level, so deep probe will have populated the device by the time the
probe is called. barebox-state however is probed at device_initcall
level and thus must take care itself to ensure the partition provider is
probed. Add a new of_partition_ensure_probed that does this. It can
handle both legacy and new style (fixed) partitions.
