I have made a first cut at supporting the Broadcom 2838 hardware random num=
ber generator, as found on the Raspberry Pi 4.

Diff: https://github.com/freebsd/freebsd/compare/master...RobCrowston:pi4-h=
wrng

This extends the existing bcm2835_rng.c driver to function on the Pi4. Unfo=
rtunately I do not have a Raspberry Pi 3 board to confirm it still works th=
ere, but on my Pi4, it generates (apparently) random numbers.

Some rough edges, but it works.
