[PATCH 5/6] hw/isa/vt82c686: Simplify removing unuseful qemu_allocate_irqs() call

[Philippe Mathieu-Daudé]

Instead of creating an input IRQ with qemu_allocate_irqs()
to pass it as output IRQ of the PIC, with its handler simply
dispatching into the "intr" output IRQ, simplify by directly
connecting the PIC to the "intr" named output.

Fixes: 3dc31cb8490 ("vt82c686: Move creation of ISA devices to the ISA bridge")
