commit 8a4205bab611b8f36b7b36aadb54849540e5f108
Author: Denis 'GNUtoo' Carikli

qemu-i440fx: Make it compile with CONFIG_DYNAMIC_CBMEM.

Note that using CONFIG_RELOCATABLE_RAMSTAGE make it fails like that:
      Loading image.
      CBFS: Decompressing stage fallback/coreboot_ram @ 0x3ffbefc0 (184400 bytes)
      Loading module at 3ffbf000 with entry 3ffbf000. filesize: 0x18db8 memsize: 0x2c050
      Processing 1703 relocs with adjust value of 0x3ffbe000
      FATAL: Essential component is missing.
    However without that configuration set it boots fine.
