Reverse the search algorithm to ensure that address mapping and IRQ
allocation logics are proper. This makes the below bugs visible sooner.
class 1. address space errors -> example:
reg = <a size_b>
ti,max-irqs = is a wrong parameter
class 2: irq-reserved list - which decides which entries in the
address space is not actually wired in
class 3: wrong list of routable-irqs.
In general allocating from max to min tends to have benefits in
ensuring the different issues that may be present in dts is easily
caught at definition time, rather than at a later point in time.
