mb/emulation/qemu-i440fx|q35: Switch to C_ENVIRONMENT_BOOTBLOCK
Useful for testing stuff in C_ENVIRONMENT_BOOTBLOCK, like
VBOOT with separate verstage.
Changes:
* Use symbols to set up CAR and STACK
* Zero CAR area
* Move BIST failure checking to cpu folder
* Rename functions where necessary
Tested:
* qemu-2.11.2 machine pc
* qemu-2.11.2 machine q35
Test result:
* BIST error reporting is still working.
* Console starts in bootblock
* SeaBios 1.11.2 as payload is still working
