Added support for the D-Link DSM-G600 RevA, and fixed the clock frequency for NSLU2 and DSMG600. Had to refresh the gateway 7001 patch due to changes in the file being patched.

+This patch adds support for the D-Link DSM-G600 Rev A.
+This is an ARM XScale IXP4xx system relatively similar to
+the NSLU2 and NAS-100D already supported by mainline. An
+important difference is Gigabit Ethernet support using
+the Via Velocity chipset.
+
+This patch is the combined work of Michael Westerhof and
+Alessandro Zummo, with contributions from Michael-Luke
+Jones. This version addresses review comments from rmk
+and Deepak Saxena.

+This patch is required as the frequency fixup in nslu2_init does not
+run sufficiently early in the boot sequence to take effect. In
+addition the dsmg600 setup code behaviour has been improved such
+that a 'fixup' routine is avoided.
