hw/hppa: Implement proper SeaBIOS version check
It's important that the SeaBIOS hppa firmware is at least at a minimal
level to ensure proper interaction between qemu and firmware.
Implement a proper firmware version check by telling SeaBIOS via the
fw_cfg interface which minimal SeaBIOS version is required by this
running qemu instance. If the firmware detects that it's too old, it
will stop.
