[PATCH 2/6] hw/isa/i82378: Simplify removing unuseful qemu_allocate_irqs() call

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

When the i82378 model was added in commit a04ff940974 ("prep:
Add i82378 PCI-to-ISA bridge emulation") the i8259 model was
not yet QOM'ified. This happened later in commit 747c70af78f
("i8259: Convert to qdev").

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, we can now simplify
and directly connect the PIC to the "intr" named output.
