random: document get_random_int() family

commit 92e507d216139b356a375afbda2824e85235e748 upstream.

Explain what these functions are for and when they offer
an advantage over get_random_bytes().

(We still need documentation on rng_is_initialized(), the
random_ready_callback system, and early boot in general.)
