RK3588 : Backport panthor / mesa for G610

@JeffyCN

Now mesa has support for the Mali-G610 we can backport the panthor driver to the 6.1 kernel.

This would allow for vulkan / gl / egl support and avoid the need for the libmali patches

I have done this myself and everything is working as expected other than chromium rkmpp integration.

Wayland / sway / hyprland display managers all work on mesa 25.0.2 with no patches.

rkmpp acceleration via gstreamer works as expected (almost zero CPU usage for 4k decoding)

@JeffyCN would you accept these changes ? Also would you be able to help debug why chromium rkmpp-v4l2 doesn't work but gstreamer rkmpp does ?
