Ubuntu merge (sort of) complete - 6.12 release

[jglathe]

An update on the state of things. We're sort of reaching maturity:

• we're on kernel 6.12 now, on the qcom-x1e-6.12 branch of Ubuntu Concept X1E 24.10. The normal Ubuntu config works with all of them. HP Omnibook is an install target that will be recognized by the installer ISO.
• Windows Dev Kit 2023 device tree is submitted for upstreaming.
• HP Omnibook X14 device tree is submitted for upstreaming.
• Board files for both are submitted for upstreaming.

With Canonical picking up the ball it will be sort of easier to get Linux installed on all of these boxes. It may also mean focussing on the things that are still an issue / don't work yet:

• Audio (built-in devices and via DisplayPort)
• DP Altmode
• RTC on the X14
• keyboard backlight and function keys on the X14

I also have a SnapDragon Dev Kit sitting here, with really unwilling DP Altmode, so no display yet. Still enough to do.
