[PATCH] hw_random: provide more information when driver loads

[PATCH] hw_random: provide more information when driver loads

[James Nelson]

This patch makes the hw_random driver a little more informative when it is starting up -
currently, there is no easy way to tell if the driver detected any hardware.

The AMD driver does mention that it found the chip - this adds the same for the VIA
and Intel sections of the driver.

Tested with an i810-equipped system.
