[PATCH] Remove old HW RNG support

This patch series replaces the old non-generic Hardware Random Number
Generator support by a fully generic RNG API.

This makes it possible to register additional RNGs from modules.  With this
patch series applied, Laptops with a bcm43xx chip (PowerBook) have a HW RNG
available now.

Additionally two new RNG drivers are added for the "ixp4xx" and "omap"
devices.  (Written by Deepak Saxena).  This patch series includes the old
patches by Deepak Saxena.

The old x86-rng driver has beed split.

The userspace RNG daemon can later be updated to select the RNG through
/sys/class/misc/hw_random/ for convenience.  For now it is sufficient to use
cat and echo -n on the sysfs attributes.
