Add support for empty ranges properties within the tree, some vendor
device trees have these, for example the ARM AArch64 Foundation Model.

Eliminate fdt_data_verify(). The verification it proceed is wrong
disallowing us to encode 64-bit register numbers.

The ranges parent bus address may just be a tag to the entry in the parent

Replace multiple nearly-identical copies of code to walk through an FDT
node's interrupts=<...> property creating resource list entries with a
single common implementation. This change makes ofw_bus_intr_to_rl() the
one true copy of that code and removes the copies of it from other places.

This also adds handling of the interrupts-extended property, which allows
specifying multiple interrupts for a node where each interrupt can have a
separate interrupt-parent. The bindings for this state that the property
cells contain an xref phandle to the interrupt parent followed by whatever
interrupt info that parent normally expects. This leads to having a
variable number of icells per interrupt in the property. For example you
could have <&intc1 1 &intc2 26 9 0 &intc3 9 4>.

Add a helper routine to depth-search the device tree for a node with a
matching 'compatible' property. This probably has a short half-life (as
do most of the fdt_ functions), but it helps solve some near-term needs
until we work out the larger problems of device instantiation order
versus the order of things in the fdt data.
