---------------------------
x86: pc: Put a stub IO device at port 0xed which the kernel can use for delays.

There was already a stub device at 0x80, the port traditionally used for an IO
delay. 0x80 is also the port used for POST codes sent by firmware, and that
may have prompted adding this port as a second option.

Testing Done

I might be confused by the weird semantics of the gem5 configuration scripts, but isn't this killing the fake device for port 0x80?

Hmm, yes. The peril of making these changes late at night when it's time to go home.
