[RFC PATCH 0/2] xen/arm: Remove recursion from dt_unreserved_regions

[Luca Fancellu <luca.fancellu@xxxxxxx>]

Hi, this is an RFC that is exploiting the new 'struct membank' interface
introduced here 2209c1e35b479dff8ed3d3161001ffdefa0a704e ("xen/arm: Introduce a
generic way to access memory bank structures") to start removing recursion
from some function, in this serie the dt_unreserved_regions is reworked for
that reason.

This is an RFC to understand if the proposed approach can be accepted.

Another function can benefit from this approach, consider_modules in
arm32/mmu/mm.c, but it might require to rework also the 'struct bootmodules'
to adhere to the new interface and have just a loop that can go through all the
different structures.

Comments are welcome.
