All Linux firmware drivers are put under "/firmware" node and it has support to populate "/firmware" node by default.
u-boot and Linux can share same DTB. In this case, driver probe for devices under "/firmware" will not be invoked as "/firmware" does not have its own "compatible" property.
This patch series scans "/firmware" node by default like "/clocks". To avoid duplication of code, first patch moves, node scan code into separate function.
This series also test to make sure "/firmware" nodes are scanned properly.
