Add functions to iterate on all property with livetree

- dev_read_next_prop
- dev_read_prop_by_prop
and
- ofnode_get_first_property
- ofnode_get_next_property

And helper: dev_for_each_property

For example:
struct ofprop property;

dev_for_each_property(property, config) {
value = dev_read_prop_by_prop(&property, &propname, &len);

or:

for (res = ofnode_get_first_property(node, &property);
!res;
res = ofnode_get_next_property(&property))
{
value = ofnode_get_property_by_prop(&property, &propname, &len);
....

This function is usefull to get phandle number contained

For example, this allows to allocate the right amount

To implement it, either of_count_phandle_with_args() or
fdtdec_parse_phandle_with_args() are used respectively
for live tree and flat tree.
By passing index = -1, these 2 functions returns the
number of phandle contained into the property list.

Add also the dev_count_phandle_with_args() based on
ofnode_count_phandle_with_args()

The return type (const u32 *) is wrong. DT property values can be

returns an opaque pointer.

dm: core: Add operations on device tree references

Since U-Boot supports both a live tree and a flat tree, we need an easy
way to access the tree without worrying about which is currently active.
To support this, U-Boot has the concept of an ofnode, which can refer
either to a live tree node or a flat tree node.

For the live tree, the reference contains a pointer to the node (struct
device_node *) or NULL if the node is invalid. For the flat tree, the
reference contains the node offset or -1 if the node is invalid.

Add a basic set of operations using ofnodes. These are implemented by
using either libfdt functions (in the case of a flat DT reference) or
the live-tree of_...() functions.

Note that it is not possible to have both live and flat references active
at the same time. As soon as the live tree is available, everything in
U-Boot should switch to using that. This avoids confusion and allows us to
assume that the type of a reference is simply based on whether we have a
live tree yet, or not.

dm: core: Add ofnode to represent device tree nodes

With live tree we need a struct device_node * to reference a node. With
