[U-Boot] [PATCH V2] misc: Tegra BPMP: support child node devices

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

The BPMP bindings allow devices to be represented as child nodes of the
BPMP node. This requires the driver to trigger scanning of its node for
those child nodes.

v2: Use dm_scan_fdt_dev() to scan sub-nodes. This function was just added.
