irqchip/irq-mvebu-icu: Add support for System Error Interrupts (SEI)

So far the ICU only handled NSR interrupts through GICP. An SEI driver
provides an MSI domain through which it is possible to raise SEI, so
let's add SEI support to the ICU driver.

Handle the NSR probe function in a more generic way to support other
type of interrupts.

Each interrupt domain is a tree domain to avoid allocation the 207
entries each time.

irqchip/irq-mvebu-icu: Support ICU subnodes

The ICU can handle several type of interrupt, each of them being handled
differently on AP side. On CP side, the ICU should be able to make the
distinction between each interrupt group by pointing to the right parent.

This is done through the introduction of new bindings, presenting the ICU
node as the parent of multiple ICU sub-nodes, each of them being an
interrupt type with a different interrupt parent. ICU interrupt 'clients'
now directly point to the right sub-node, avoiding the need for the extra
ICU_GRP_* parameter.

ICU subnodes are probed automatically with devm_platform_populate(). If
the node as no child, the probe function for NSRs will still be called
'manually' in order to preserve backward compatibility with DT using the
old binding.

irqchip/irq-mvebu-icu: Disociate ICU and NSR

NSR (non-secure interrupts) are handled in the ICU driver like if there
was only this type of interrupt in the ICU. Change this behavior to
prepare the introduction of SEI (System Error Interrupts) support by
moving the NSR code in a separate function. This is done under the form
of a 'probe' function to ease future migration to NSR/SEI being platform
devices part of the ICU. The 'icu' structure is passed as driver data
and not as a parameter for the same reason.

irqchip/irq-mvebu-icu: Fix wrong private data retrieval

The irq_domain structure has an host_data pointer that just stores
private data. It is meant to not be touched by the IRQ core. However,
when it comes to MSI, the MSI layer adds its own private data there
with a structure that also has a host_data pointer.

Because this IRQ domain is an MSI domain, to access private data we
should do a d->host_data->host_data, also wrapped as
'platform_msi_get_host_data()'.

This bug was lying there silently because the 'icu' structure retrieved
this way was just called by dev_err(), only producing a
'(NULL device *):' output on the console.
