sysfw: remove read-only pc_sysfw_flash_vs_rom_bug_compatible

The variable is not written anymore.

This cleans up after 9e1c2ec (which accidentally left variable
pc_sysfw_flash_vs_rom_bug_compatible behind, value always zero), and

fdc: Fix inheritence for SUNW,fdtwo

Since commit dd3be7420774f7dc8f37a96ca24d07f0b6f31b3b SUNW,fdtwo's
initfn (realizefn since 940194c2369e50d91d1abf6f36d43853eea5e539)
was using SYSBUS_FDC() cast. This uses type sysbus-fdc rather than
SUNW,fdtwo.

Fix this by letting SUNW,fdtwo and sysbus-fdc both inherit from an...

dataplane: refuse to start if device is already in use

Dataplane must check whether a block device is in use before launching
the dataplane thread. This is necessary since the thread does not
synchronize with the main loop and I/O requests could cause corruption....

dataplane: enable virtio-blk x-data-plane=on live migration

Although the dataplane thread does not cooperate with dirty memory

The firmware commonly used with MIPS Malta boards (YAMON) reads the
