Add LM99 support to the lm90 driver

Hi Greg,

The following patch adds support for the LM99 chip to the lm90 driver, on popular request. The nVidia GeForce FX 5900 series cards have such a chip on-board for monitoring the GPU temperature.

Relevant pointers:

Additional effects of the patch:

* Do not consider the lm90 driver experimental anymore. I have had enough testers and not a single problem report, the driver is working OK.

* Support the LM89. According to the datasheets, it is exactly the same chip as the LM99 (to the chip ID). We've never seen this chip in a computer so far, but it doesn't cost anything to support it (actually we cannot not support it, since we have no way to differenciate with the LM99).

* Scan two addresses instead of one. The LM99 and LM89 have a "-1" variant using an alternate address.

* Update copyright year.

* Reword the identification code a bit. It is hopefully slightly less unreadable.

This patch was successfully tested by Corey Hickey.

A similar patch has been applied to our CVS repository for Linux 2.4. Our user-space tools have been updated as well.

Please apply,
thanks.
