Jason A. Donenfeld 6e1cb84cc6 random: pull add_hwgenerator_randomness() declaration into random.h ...

commit b777c38239fec5a528e59f55b379e31b1a187524 upstream.

add_hwgenerator_randomness() is a function implemented and documented
inside of random.c. It is the way that hardware RNGs push data into it.
Therefore, it should be declared in random.h. Otherwise sparse complains
with:

random.c:1137:6: warning: symbol 'add_hwgenerator_randomness' was not declared. Should it be static?

The alternative would be to include hw_random.h into random.c, but that
wouldn't really be good for anything except slowing down compile time.
