[U-Boot] [RFC PATCH 05/29] drivers: pci-uclass: make DT subnode parse optional

[Suneel Garapati]

From: Suneel Garapati <sgarapati at marvell.com>

Parse subnode DT properties only if parent node is valid.
Otherwise, assert is triggered on ofnode_valid in ofnode_first_subnode
from dev_for_each_subnode.
