Add generic qemu detection
This patch adds support for detecting whenever SeaBIOS runs on qemu
or not. This is done by looking at the northbridge (pci device 00:00.0)
and check the subsystem id. Most pci devices emulated by qemu -- the
two northbridges i440fx and q35 included -- have a subsystem id of
"1af4:1100".
In case the subsystem ID matches set PF_QEMU, log a message (including
the northbridge found while being at it) and also check for kvm.
