Following the idea from 7747b3fa36d3 ("generic: add bcm2835-rng quality
patch") and 9dc84018eeef ("bcm27xx: remove urngd package") this patch
allows kernel to directly use HW RNG and provide enough entropy from
/dev/random without urngd and/or rng-tools.
I am not sending this upstream as I have no idea how to estimate quality
properly.
