Cut and sewing work around mailing list/libreelec patches to include a minimum set of patches that attempt to solve the various issues with HDMI on rockchip64 family. This affects both current kernel 6.6 and edge kernel 6.8.

One kind guy tested the kernel package on rockpro64 and reported success: https://forum.armbian.com/topic/26818-opi-4-lts-no-hdmi-output/?do=findComment&comment=189646

Also remove a patch named "rk356x-vop2-support", that was not about vop2 support but rather tweaks the HDMI phy timings and code because it has been already included in this more general clock fixes.
