SeaBIOS: update stable release from 1.8.2 to 1.9.0

* The default boot menu key is now the ESC key (instead of F12)
    * Initial support for Trusted Platform Module (TPM) hardware and BIOS calls
    * Initial support for chain loading SeaBIOS from Grub (via multiboot
      support)
    * Initial support for booting from SD cards on real hardware
    * virtio 1.0 device support
    * The build will no longer include the build hostname or build time on
      "clean" builds.  This makes the build binaries more "reproducible".
    * Basic support for running SeaBIOS on Baytrail Chromebooks
    * SeaVGABIOS improvements:
        * Improved support for old versions of x86emu (the "leal"
          instruction is now emulated)
    * Several bug fixes and code cleanups
