Linux kernel CF9 reboot is doing things like:
- read value from 0xcf9
- mask out the value according to the reboot type (warm vs cold)
- BIT OR the value with reboot code
- write the value to 0xcf9
If there are two reboot event and the first one is cold
reboot and the second one is warm reboot, vsbl query
reboot type after the second one and will get code reboot
instead of warm reboot.
We should clear the data of 0xcf9 if guest request cold reboot.

There are bootloaders require cold reboot as ACPI reboot
instead of warm reboot.
So we set 0xE to reset value of FADT to make ACPI reboot
cold reboot.

so that these data structures cannot be overwritten while

Writing PCIR_BIOS is to get PCI ROM resource length. Ingore the request
as it's not support currently. Else, guest might get wrong information
about the PCI ROM resource.
