Thanks Will for pointing this. I agree with you and like to be added as
reviewer for this.

Since arch_topology.c was mostly added for ARM/ARM64 and by Juri Lelli 
(who is no longer with ARM) and I did review the initial version, I would
like to assume maintenance for this file if both Juri and Greg are OK
with it so that I can keep an eye on this as we expect more changes to
this both for ARM and RISC-V. I am fine if anyone who has contributed
more to this file wants to maintain.
