Hum, with my suggestion, we lose the opportunity for drivers to
rewrite completely their "deps".
I doubt we have cases where it really matters, but if this revealed to
be necessary, such driver may be directly referenced in
drivers/meson.build like we do for common/cnxk & friends.

To illustrate the idea, I pushed your series along patches of mine
(target is v23.11) in my github repo.
