[Xen-devel] [RFC 04/22] xen/arm: gic-v3: Use the domain redistributor information to make the DT node

[Julien Grall <julien.grall@xxxxxxxxxx>]

It's not neccessary to get again from the hardware DT the redistributor
informations. We already have it stored in the gic_info and the domain.

Use the latter to be consistent with the rest of the function.
