[PATCH v2] PCI: of: Downgrade error message on missing of_root node

When CONFIG_PCI_DYNAMIC_OF_NODES is enabled, an error message
is generated if no 'of_root' node is defined.

On DT-based systems, this cannot happen as a root DT node is
always present. On ACPI-based systems, this is not a true error
because a DT is not used.

Downgrade the pr_err() to pr_info() and reword the message text
to be less context specific.
