    soc/qualcomm/ipq40xx: Return NULL for cbmem_top if DRAM is not initialized
    
    DRAM initialization on gale requires ipq blobs to be
    loaded from cbfs. vboot_locator first checks cbmem_find to see if cbmem is
    initialized and contains selected region info, else it falls back to
    vboot work buffer.
    
    Since cbmem_find calls into cbmem_top to identify the location of
    cbmem area, board/chipset is expected to return NULL until the backing
    store is ready, which in this case until DRAM is initialized in
    romstage, return NULL for cbmem_top.
