serial-isa: Use MAX_ISA_SERIAL_PORTS instead of MAX_SERIAL_PORTS
The ISA serial port handling in serial-isa.c imposes a limit of 4 serial ports. This is because we only know of 4 IO port and IRQ settings for them, and is unrelated to the generic MAX_SERIAL_PORTS limit, though they happen to both be set at 4 currently. Use a new MAX_ISA_SERIAL_PORTS wherever that is the correct limit to be checking against.
