mb/google/fizz: Enable VMX
We are enabling at the kernel level, but that is triggering an issue where FSP expects it to be disabled so it forces a cold reboot on every warm reboot, clearing the ramoops logs. Enabling in BIOS so it matches what the kernel expects.
This is the same change that were done for eve: https://review.coreboot.org/#/c/22449/
