The Linux kernel already has the concept of IRQ domain, wherein a
component can expose a set of IRQs which are managed by a particular
interrupt controller chip or other subsystem. The PCI driver exposes
the notion of an IRQ domain for Message-Signaled Interrupts (MSI) from
PCI Express devices. This patch exposes the functions which are
necessary for creating a MSI IRQ domain within a module.

Since 3cb96f0c9733 ('x86/hpet: Enhance HPET IRQ to support
hierarchical irqdomains') hpet_msi_capability_lookup() uses
hpet_assign_irq(). The latter initializes irq_alloc_info on stack, but
passes a NULL pointer to irq_domain_alloc_irqs(), which causes a NULL
pointer dereference later in hpet_msi_get_hwirq().
Pass the pointer to the irq_alloc_info irq_domain_alloc_irqs().

Refine the interfaces to create IRQ for DMAR unit. It's a preparation
for converting DMAR IRQ to hierarchical irqdomain on x86.
It also moves dmar_alloc_hwirq()/dmar_free_hwirq() from irq_remapping.h
to dmar.h. They are not irq_remapping specific.

Use new irqdomain interfaces to allocate/free IRQ for DMAR and interrupt
remapping, so we can remove GENERIC_IRQ_LEGACY_ALLOC_HWIRQ later.
The private definitions of irq_alloc_hwirqs()/irq_free_hwirqs() are a
temporary solution, they will be removed once we have converted the
interrupt remapping driver to use irqdomain framework.
