The m68k mcf_intc interrupt controller currently implements its
inbound IRQ lines by calling qemu_allocate_irqs() in mcf_intc_init().
This results in leaks like this:
Direct leak of 2944 byte(s) in 46 object(s) allocated from:
#0 0x5cf95ec15323 in malloc (/home/pm215/qemu/build/san/qemu-system-m68k+0xf9e323) (BuildId: 18d55ef8ea9856e68ee30802078af5050b8b06c5)

#4 0x5cf95f6aa62e in qemu_extend_irqs /home/pm215/qemu/build/san/../../hw/core/irq.c:79:16

This isn't an important leak, as it is memory we allocate once at
QEMU startup and that has to stay live for the lifetime of the
system. However it does point at a code improvement.
Modernise this to have the device itself create inbound GPIOs with
qdev_init_gpio_in() that the board can then refer to and wire up
individually.
As the device is used in only a single board, we can update device
and board in a single patch rather than having to try to figure out
some way to change the API more piecemeal.
