The DPAA bus support code put out messages like:
dpaax: read_memory_node(): Unable to glob device-tree memory node:
(/proc/device-tree/memory[@0-9]*/reg)(3)
dpaax: PA->VA translation not available;
dpaax: Expect performance impact.
These are unnecessary and likely to confuse the end user.
Fix this by doing nothing if bus is empty.
