        src/sys/dev/pci: hifn7751.c hifn7751var.h

Log Message:
Rework hifn(4) RNG logic.

Previously we would read 34 bits of entropy into the pool and stop,
never to try again.  This change finishes the conversion to an
on-demand source, although we still use a callout to (a) try again in
another second if the 7811 FIFO was emptied, and (b) wait at least
0.4 sec after we start the RNG to read anything from it as the
alleged documentation allegedly recommends.
