PATCH 1/1 new cpufreq driver for NatSemi Geode

I write a new cpufreq driver for NatSemi Geode.
This driver supports old Cyrix MediaGXm or NatSemi Geode GX series with CS5530,CS5530A, CS5520 and CS5510.

This driver detects a chipset and does thing that suitable for chip. I test it on MediaGXm 200MHz with CS5520 and Geode GX1 with CS5520.

My code based on Zwane Mwaikambo's patch. I re-write almost.

Please merge this driver into cpufreq project patchset.

A patch for 2.5.53 is attatched and you can download driver file only from
http://www.da-cha.org/geode/gx-suspmod.c
