at least the rk3588 has multiple v{d/e{.}pu blocks, so this compatible
is very misleading. As you mention in the commit description already,
this describes the vdpu121, so can we please use that in the compatible
as well to distinguish this one from the others that hopefully will come
later?

Thanks
