Text value for the RS232 interface chip. One of:

• 8250 - original, 1-byte buffer, one interrupt per byte received
• 16450 - 16550 but with no FIFO buffer
• 16550 - early 16550 with broken FIFO buffer, effectively a 16450
• 16550A - fixed 16550 with working FIFO buffer
• 16650 - early 16650 with broken FIFO buffer
• 16650V2 - fixed 16650 with working FIFO buffer

Add others to this list as needed - try to be as generic as possible, avoiding part names and using interface names instead.
