bus_set_pass — raise the bus pass level
The bus_set_pass function is called during boot to raise the bus pass
level to pass. The function will rescan the device tree for each pass
level between the current pass level and the new level that has at least
one associated driver. The device tree rescans are implemented by
invoking the BUS_NEW_PASS(9) method on the root bus device.
