[PULL 57/83] hw/isa/piix4: Remove unused inbound ISA interrupt lines

[Michael S. Tsirkin]

From: Bernhard Beschow <shentey@gmail.com>

The Malta board, which is the only user of PIIX4, doesn't connect to the
exported interrupt lines. PIIX3 doesn't expose such interrupt lines
either, so remove them for PIIX4 for simplicity and consistency.
