hw/isa/i82378: Remove intermediate IRQ forwarder
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"). Directly dispatch ISA IRQs to 'cpu_intr' output IRQ by removing the intermediate i82378_request_out0_irq() handler. Rename ISA IRQs array as 'isa_irqs_in' to emphasize these are input IRQs.
