drivers/generic/ioapic: Drop poor implementation
This disables MP table generation for the affected boards
since interrupt routing entries would now be completely missing.
The mechanism itself is flawed and redundant. The mapping
of integrated PCI devices' INTx pins to IOAPIC pins is
dependent of configuration registers and needs not appear
in the devicetree.cb files at all.
The write_smp_table implementation would skip writing
any entry delivering to destination IOAPIC ID 0. This
does not follow MP table specification.
There were duplicate calls to register_new_ioapic_gsi0(),
with another present under southbridge LPC device.
