Initialize CBMEM early.

We want to be able to share data between different phases of firmware
    (rom stage/ram stage/payload). Coreboot CBMEM seems an appropriate
    location for this data, but normally it is not initialized
    until coreboot reaches the ram stage.

This change initializes the CBMEM while still in rom stage in
    case CONFIG_EARLY_CBMEM_INIT is set.

Note that there is a discrepancy in how coreboot determines the
    size of DRAM at rom and ram stages, get_top_of_ram() is used at
    rom stage and is not defined for all platforms. Those platforms
    will have to define this function should they enable the
    CONFIG_EARLY_CBMEM_INIT flag.
