The patch to call mp_config_acpi_gsi() from the ACPI IRQ registration
code never got mainline because there were open discussions about it.

This call is needed to properly update the kernel's copy of the mptable,
when the update_mptable boot parameter is needed.

Now that the dust has settled with the APIC unification, and since there
were no objections when the patch was re-submitted, try this again.

We already have a per cpu vector on 32-bit via recent changes, and
don't need this trick any more (which trick obfuscates the real GSI
mappings and which only triggers on larger systems to begin with):

On 3 ioapic system (24 per ioapic) before patch I got:

on the home node of the device.

If no device has been passed down, we assume it's a platform
device and use the boot node ID for the IRQ descriptor.

This simplifies the node awareness of the code. All our allocators

irq_set_affinity() and move_masked_irq() try to assign affinity
before calling chip set_affinity(). Some archs are assigning it
in ->set_affinity() again.

We do something like:

 cpumask_cpy(desc->affinity, mask);
 desc->chip->set_affinity(mask);

But in the failure path, affinity should not be touched - otherwise
we'll end up with a different affinity mask despite the failure to
migrate the IRQ.

So try to update the afffinity only if set_affinity returns with 0.
Also call irq_set_thread_affinity accordingly.

v2: update after "irq, x86: Remove IRQ_DISABLED check in process context IRQ move"
v3: according to Ingo, change set_affinity() in irq_chip should return int.
v4: update comments by removing moving irq_desc code.

The original feature of migrating irq_desc dynamic was too fragile
and was causing problems: it caused crashes on systems with lots of
cards with MSI-X when user-space irq-balancer was enabled.

We now have new patches that create irq_desc according to device
numa node. This patch removes the leftover bits of the dynamic balancer.
