NanoPi R6S: Update blobs to fix issue

[ColorfulRhino]

Description

FriendlyElec ships their devices with the latest blobs. Trying to run an Armbian image on this board with the old blobs might cause issues.
@rpardini run into those issues with the NanoPC T6 and fixed it in #6711

Yes, and... this v1.16 + v1.45 seems pretty prevalent. We had troubles once when bumping the default version (in rk64_common?) but that was about one specific version that had difficulties in certain conditions, afaik already fixed many versions ago -- so we started with board-specific bumps. Maybe it's time to revisit and lower maintenance (eg, bump the default, remove from boards).

Yeah I thought about this too, but then remembered that I read in the past that it might cause some issues in certain edge case scenarios.
I'd be fine with updating the default in the family config. I think trying to avoid all problems regarding to the blobs is impossible, since as we saw now also vendors update their blobs and ship devices with them :) So even relying on old blobs, which is not a good practice anyway imo, would not solve this, even though it might mitigate some other edge case problem.

Also at some point we will probably be able to build U-Boot completely open source without these blobs. I'm sure that will cause a few new issues, but that's just how it is if you want progess 😄
Ship it and fix as we go.
