2018-07-26device: add child traversal helper functionAaron Durbin
Add a function, dev_bus_each_child(), which walks through all the children for a given bus of a device. This helper allows one to walk through all the children of a given device's bus.

2018-05-25device: Rename device_simple.c --> device_const.cNico Huber
In early stages (pre ramstage), we have two notions of devices. To access the hardware, "simple device" handles are used. These are plain numbers. To access the static information of the device tree, we use `struct device` pointers. This is referred to as DEVTREE_EARLY in the code. This file is about the latter and its name reflects that the tree remains unmodified.
