soc/amd/phoenix: Disable APOB Cache
There is a data abort in ABL when the memory training data is used from APOB Cache. Disable APOB Cache until the cause is identified. The downside of this change is that the memory training happens in every boot cycle. BUG=b:290763369 TEST=Build BIOS image and boot to OS in Myst. Trigger a reboot from AP console and ensure that the system boots to OS.
