Refine the interfaces to create IRQ for DMAR unit. It's a preparation
for converting DMAR IRQ to hierarchy 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.

Introduce new interfaces for interrupt remapping drivers to support
hierarchy irqdomain:
1) irq_remapping_get_ir_irq_domain(): get irqdomain associated with an
interrupt remapping unit. IOAPIC/HPET drivers use this interface to
get parent interrupt remapping irqdomain.
2)
Use new irqdomain interfaces to allocate/free IRQ for DMAR and interrupt
remapping, so we could kill GENERIC_IRQ_LEGACY_ALLOC_HWIRQ later.
The private definition of irq_alloc_hwirqs()/irq_free_hwirqs() are
temporary solution, it will be removed once we have converted interrupt
remapping driver to
Enhance MSI code to support hierarchy irqdomain, it helps to make
the architecture more clear.

Hello Marek,
I wanted to test your IOMMU series on an Exynos5420 Peach Pit but the
kernel hangs with your series + dependencies on top of 3.19-rc5.
Bisecting I found that $subject is the offending commit. I've pushed
my test branch [0] in case I missed something.
