This patch series enables support for the HWRNG included on the Raspberry
Pi 4. It is simply a rebase of Stefan's branch [1]. I went ahead and
tested this out on a Pi 4. Prior to this patch series, attempting to use
the hwrng gives:
$ head -c 2 /dev/hwrng
head: /dev/hwrng: Input/output error
After this patch, the same command gives two random bytes.
