BALATON Zoltan 7e01bd80c1 hw/isa/vt82c686: Bring back via_isa_set_irq() ... The VIA integrated south bridge chips combine several functions and allow routing their interrupts to any of the ISA IRQs also allowing multiple sources to share the same ISA IRQ. E.g. pegasos2 firmware configures everything to use IRQ 9 but amigaone routes them to separate ISA IRQs so the current simplified routing does not work. Bring back via_isa_set_irq() and change it to take the component that wants to change an IRQ and keep track of interrupt status of each source separately and do the mapping to ISA IRQ within the ISA bridge. This may not handle cases when an ISA IRQ is controlled by devices directly, not going through via_isa_set_irq() such as serial, parallel or keyboard but these IRQs being conventionally fixed are not likely to be change by guests or share with other devices so this does not cause a problem in practice. This reverts commit 4e5a20b6da.
