Instead of reusing the same reg parsing code, create one, common function
that puts reg contents to the resource list. Address cells and size cells
are passed rather than acquired here so that any bus can have different
default values.

After resource allocation and release, resource list entry
stays non-NULL. This causes panic in ofwbus_alloc_resource()
on subsequent resource allocation.
Clean appropriate list entry on release to avoid this.

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>.

fixes FDT on x86 and will make coexistence with ACPI on ARM systems easier.
SPARC is unchanged.
