[PATCH v2 24/40] lasips2: introduce port IRQ and new lasips2_port_init() function

[Mark Cave-Ayland]

Introduce a new lasips2_port_init() QOM init function for the LASIPS2_PORT type
and use it to initialise a new gpio for use as a port IRQ. Add a new qemu_irq
representing the gpio as a new irq field within LASIPS2Port.
