arch/x86: Enable support for IOAPIC devices

On platforms with multiple IOAPICs the GSI base must not be
linear, which is currently assumed by acpi_create_madt_ioapic_from_hw().

Integrate the existing struct device DEVICE_PATH_IOAPIC type and allow
to assign custom GSI bases for each IOAPIC. Write out the IOAPIC devices
into the MADT table if any.

For now, since no platform adds IOAPIC devices, the existing behaviour
remains the same. Allows to get rid of soc_get_ioapic_info().
