[Qemu-devel] [PATCH 11/13] superio: Don't use MAX_SERIAL_PORTS for serial port limit |

The superio device has a limit on the number of serial
ports it supports which is really only there because
it has a fixed-size array serial[]. This limit isn't
related particularly to the global MAX_SERIAL_PORTS limit,
so use a different #define for it.
(In practice the users of superio only ever want 2 serial ports.)
