[coreboot] [PATCH 4/4] Geode GX2 auto DRAM detect patch V2

[Nils]

This patch changes Geode GX2 to use the auto DRAM detect code
from Geode LX and changes the boards to use it.
It also  adds a processor speed setting function in human 
readable Mhz and removes the useless and broken PLLMSR settings.
(the processor speed was hardcoded to 366Mhz in pll_reset.c)
