Yea that is pretty confusing. Alright, I'll retitle that to something
like:

x86/setup: Allow passing RNG seeds via setup data

Hopefully that matches more, considering the function that does the work
is called "parse_setup_data".

(I'll wait some more time before posting yet another v+1 with that
change, in case others have more feedback.)
