dm: core: Scan "/firmware" node by default

Browse Source 
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 scans "/firmware" node by default like "/clocks".
