As mentioned by Noralf UART1 is quite commonly used on Compute Modules.
Proper driver - perhaps modelled as a bus - seems like a prerequisite
for this work. You are also not using IRQ mux in DT binding example
which is very misleading.
Do we have any indication weather this AUX hardware is available on
RPi2 as well? IIRC bcm2836 differs only in CPU cores, peripherals
remain identical. Perhaps this driver could be used on RPi2 and
naming it 283x would be more appropriate?
