The 8250 BCM7271 UART is not a direct match to PORT_16550A and other generic ports do not match its hardware capabilities. PORT_ALTR matches the rx trigger levels, but its vendor configurations are not compatible. Unfortunately this means we need to create another port to fully capture the hardware capabilities of the BCM7271 UART. To alleviate some latency pressures, we default the rx trigger level to 8.
