Currently, UEFI sets up MMUs after initializing serial and figuring out what memory is usable or not. This PR splits it into two stages where the initial memory map is created with just UEFI CO and a few other regions needed for basic operations including serial logging. After figuring out what DRAM can be used by UEFI, the memory map is updated.
