Add a patch series to support VEPU121/VPU121, which mainly enables hardware decoding for H.264.
It can also decode MPEG2 and VP8 as well as do JPEG encoding.
Move kernel patch folder to archive/rockchip-rk3588-${KERNEL_MAJOR_MINOR} which is the default.
Also rename kernel config to linux-rockchip-rk3588-${KERNEL_MAJOR_MINOR}
Since the `edge` kernel branch often uses RC kernels, introduce a more stable `current` branch.
This branch should not be RC kernels and it also should move to an LTS kernel once released.
Patches are from the Linux Rockchip Mailing List, submitted by Alexey
Charkov. [1]
Notable improvements from changelog:
- Moved the TSADC enablement to per-board .dts/.dtsi files
- Dropped extra "inefficient" OPPs (same voltage - lower frequencies)
- Dropped second passive cooling trips altogether to keep things simple
- Added a cooling map for passive GPU cooling (in a separate patch)
- Added regulator coupling for EVB1 and QuartzPro64
Also enable automatic fan control on Rock 5B.

"general-add-overlay-compilation-support.patch" became obsolete in
Linux 6.9 (see AR-2352 [1]). Fix this problem:
- Rename *.dts sources in overlay directory to *.dtso
- Change "target +=" line to "dts-y +=" in overlay Makefile
- Remove "always +=" line in overlay Makefile
- Add .scr compilation support in kernel scripts/Makefile.lib
- Patch kernel scripts/Makefile.dtbinst to avoid flattening overlay
directory
For the last two points, see
general-add-overlay-compilation-support.patch

- Bump mainline kernel from 6.10-rc1 to 6.10-rc2
- Remove patches which are now mainlined
- Re-number "fix-initial-PERST-GPIO-value" patch as per number
ordering seen in 0000.patching_config.yaml
- Rewrite kernel config
- `common_defaults_for_mainline` already sets KERNELPATCHDIR='archive/s5p6818-4.14' thus this symlink is not necessary
- 1 step closer to a clean `patch/kernel` dir, when we could finally get rid of `archive/`
