meson: kernel update: legacy -> 6.6, current -> 6.12

[domin144]

Description

Make 6.6 kernel a legacy version. Add kernel 6.12 as a new current version.

The patches for 6.12 are moved straight from 6.10 and apply cleanly.

This is a follow up to #7501 and should not be merged earlier.

How Has This Been Tested?

This change was tested on MXQ tv box clone. Following functionality was tested:

• boot from USB,
• HDMI output,
• USB keyboard and mouse,
• wired network,
• SSH connection

Tested with Odroid C1, same functionalities, but boot from SD card.

I'd recommend legacy go to 6.6, not 6.10. As 6.6 is an LTS kernel it still receives security updates versus 6.10 which is long ago dead. And I feel this is more consistent with the other families like meson64.

BTW, my commit was squashed with mighty force :) Rename those two below to .csc

Change Odroid C1 and Onecloud to community supported as build now passes

Apologies, I didn't notice the commit. It should be back there now.

No worries, happens.

I'd recommend legacy go to 6.6

Well, the problem is that patch-set for 6.6 is broken, was broken before thus it was disabled. I prepared PR with removal of legacy 6.6 kernel for those targets. No point in resolving legacy kernel functioning.
