irqdomain: Add missing NULL pointer check in irq_domain_create_hierarchy()

The recent switch to per-domain locking caused a NULL dereference in
irq_domain_create_hierarchy(), as Xen code is calling
msi_create_irq_domain() with a NULL parent pointer.

Fix that by testing parent to be set before dereferencing it. For a
non-existing parent the irqdomain's root will stay to point to
itself.

which Jens asked to take along with the librarization

- Improve irqdomain locking to close a number race conditions which
can be observed with massive parallel device driver probing

- Enforce and document the semantics of disable_irq() which cannot be
invoked safely from non-sleepable context

- Move the IPI multiplexing code from the Apple AIC driver into the
core, so it can be reused by RISCV

Drivers:

- Plug OF node refcounting leaks in various drivers

drivers

- The usual small fixes and improvements

irqdomain: Switch to per-domain locking

The IRQ domain structures are currently protected by the global
irq_domain_mutex. Switch to using more fine-grained per-domain locking,
which can speed up parallel probing by reducing lock contention.

On a recent arm64 laptop, the total time spent waiting for the locks
during boot drops from 160 to 40 ms on average, while the maximum
aggregate wait time drops from 550 to 90 ms over ten runs for example.

Note that the domain lock of the root domain (innermost domain) must be
used for hierarchical domains. For non-hierarchical domains (as for root
domains), the new root pointer is set to the domain itself so that
&domain->root->mutex always points to the right lock.

Also note that hierarchical domains should be constructed using
irq_domain_create_hierarchy() (or irq_domain_add_hierarchy()) to avoid
having racing allocations access a not fully initialised domain. As a
safeguard, the lockdep assertion in irq_domain_set_mapping() will catch
any offenders that also fail to set the root domain pointer.

irqdomain: Clean up irq_domain_push/pop_irq()

The irq_domain_push_irq() interface is used to add a new (outmost) level
to a hierarchical domain after IRQs have been allocated.

Possibly due to differing mental images of hierarchical domains, the
names used for the irq_data variables make these functions much harder
to understand than what they need to be.

Rename the struct irq_data pointer to the data embedded in the
descriptor as simply 'irq_data' and refer to the data allocated by this
interface as 'parent_irq_data' so that the names reflect how
hierarchical domains are implemented.

irqdomain: Fix domain registration race

Hierarchical domains created using irq_domain_create_hierarchy() are
currently added to the domain list before having been fully initialised.

This specifically means that a racing allocation request might fail to
allocate irq data for the inner domains of a hierarchy in case the
parent domain pointer has not yet been set up.

Note that this is not really any issue for irqchip drivers that are
registered early (e.g. via IRQCHIP_DECLARE() or IRQCHIP_ACPI_DECLARE())
but could potentially cause trouble with drivers that are registered
later (e.g. modular drivers using IRQCHIP_PLATFORM_DRIVER_BEGIN(),
gpiochip drivers, etc.).
