Jan Čermák 9a760a2e28 Update all platforms to latest stable Linux 6.12 (#3850)
* Upgrade Rockchip platforms to Linux 6.12

Upgrade all Rockchip boards to latest 6.12. Patches for M1S can be dropped, its
DTS has been merged. Same goes for the Rockchip TRNG, it only had to be enabled
in the Green DTS. Patch for broken combphy has been updated for 6.12.y.

* Remove deprecated and nonsense symbols from Rockchip defconfig

Many symbols have been removed between 6.6 and 6.12. Most of them have no use
in Rockchip defconfig, or should be set by other kernel fragments anyway.
Remove all of them, with the exception of USB_ONBOARD_HUB (which was renamed to
USB_ONBOARD_DEV) and FSCACHE (which was changed from tristate to bool).

* Update generic-aarch64 to Linux 6.12

* Update Amlogic-based ODROID boards to Linux 6.12

Removed couple of deprecated/unrelated kernel options.

* Update VIM3 to Linux 6.12

Cleaned up symbols unrelated/deprecated in 6.12 from defconfig.

* Update ODROID-XU4 to Linux 6.12

The usual defconfigs suspects had to been removed and the regulator patch for
ethernet needed a minor update after refactoring in upstream.

* Update Tinker to Linux 6.12

Needed defconfig cleanup for 6.12, otherwise no changes.

* Update x86 and OVA to latest 6.12 release

This way the extra patches directory can be removed too.

* Remove 6.6.73 patches

* Refresh all linux patch series against 6.12.11 sources

* Reenable HW RNG on M1S to speed up boot

The TRNG on RK3566 supposedly [1] has low quality, that's why it's disabled in
upstream for this SoC. We had it enabled in the past and without it, the boot
is delayed by quite a lot. Enable it again for now and investigate the RNG
issues later.

* Also remove CACHEFILES module from Rockchip config

It was only enabled for Rockchip and Tinker, and to my knowledge there is no
cachefiles daemon or anything other in the userspace that's using it.

* Remove unused 6.6.y fragments

Since we only have 6.6.y for Raspberry Pi now, it doesn't need the Rockchip and
wireless PCI fragments.
