Thank you for pointing this out. wrt resets the GIC has two signals
(which I learnt lately when the dependency path was accepted). Earlier
discussion in irc with Sudeep pointed out that there wouldn't be any
use case of having GIC resets in DTSI, so either we drop the resets
property in DT binding doc or correct it.

Let me know your thoughts on this and how we proceed further.

Cheers,
Prabhakar
