serial: max310x: Support IRQ sharing with other devices According to my chip's datasheet [1], the IRQ output is an open collector pin which is suitable for sharing with other chips. The chip also has a register which indicates which UART performed a change and the driver checks that register already, so we have everything what is needed to effectively share the IRQ GPIO.
