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 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.
