Rockchip 32bit and rk322x families consolidation

[paolosabatino]

Description

Big pull request that consolidates rockchip 32bit and rk322x families together, for less painful kernel patch adaption during maintance cycles.

Jira reference number AR-1988

Despite this is the minor nightmarish part of the rockchip patches archive, consolidation could and has been done.

In particular, this PR do:

• merge patches from rockchip and rk322x families for current and edge kernels, moving everything into rockchipfamily
• migrate edge kernel rockchip-6.6 into patch series, rename all patches with more understandable names with alphabetical prefixes in place of numeric ones (sunxi inspired)
• implement new style dt and overlay directories for edge and current kernels to leverage the build system automatic makefile handling
• rework kernel configs for both edge and current: some things have been added, some removed, but will require some fine tuning that will be subject of another PR probably
• adjust patches for tinkerboard to remove some cruft and overclocking, cleaning up dmesg also
• fix rk322x dmc to avoid lockup on rk3288
• remove non-LTS rk322x archives from patch directory; remaining rk322x kernel archives can be removed in the future as well, since they are kept only for historical purposes and not in use anymore; also removes rk322x legacy, current and edge symlinks
• remove non-LTS rockchip archives from patch directory (acutally the only removed leftover was rockchip-6.5)
• remove legacy kernel target for rk322x-box
• add gen-series.sh script in tools directory (it is a naive tool to create patch series from scratch when you don't want to rebase everything, script is fully commented and usage help provided also)

How Has This Been Tested?

• Debian Bookworm image built and tested for rk322x-box
• Debian Bookworm image built and tested for tinkerboard
• Ubuntu Jammy image built and tested for rk322x-box
• Ubuntu Jammy image built and tested for tinkerboard
• Several edge 6.6 and current 6.1 kernel compilations
• Cores, gpu, hdmi, hdmi audio, ethernet, wifi, hardware decoding, usb tested on tinkerboard current 6.1
• Cores, gpu, hdmi, hdmi audio, ethernet, wifi, hardware decoding, usb tested on tinkerboard edge 6.6
• Cores, gpu, hdmi, hdmi audio, ethernet, wifi, hardware decoding, usb tested on rk322x-box current 6.1
• Cores, gpu, hdmi, hdmi audio, ethernet, wifi, hardware decoding, usb tested on rk322x-box edge 6.6

Checklist:

• My code follows the style guidelines of this project
• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation
• My changes generate no new warnings
• Any dependent changes have been merged and published in downstream modules

I have left documentation and Any dependent changes have been merged and published in downstream modules checkboxes unchecked because I'm just not sure:

• if there is any documentation that involved rk322x that should be changed (but I guess there isn't any)
• if there is the need to change in the automatic image building machinery, but I guess not, since the rk322x-box board configuration has been just changed from rk322x to rockchip family and that should suffice to avoid building rk322x kernels

What a labor of love @paolosabatino - merge it!

Thanks @rpardini!
Could you also accept again the PR? I accidentally pushed another commit to fix some kernel configs and made the previous acceptation stale, sorry!
