Split interrupt handler into PCI MSIX-specific and generic functions,
for adding non-MSIX handlers in the future. Move MSIX init code
together,, out of generic init path.

gasket_alloc_dev can retrieve the device name from the parent parameter,
a separate parameter isn't needed for this. Rename the variable to
better reflect its meaning, as the name of the parent device for which a
gasket device is being allocated.

Pass the gasket driver descriptor to the interrupt init function, rather
than exploding out separate parameters from various fields of that
structure. This allows us to make more localized changes to the types
of interrupts supported (MSIX vs. wire, etc.) without affecting

Use of readl() is deprecated; readl_relaxed() with appropriate memory
barriers is preferred. Switch to relaxed reads and writes for better
performance as well. Memory barriers required for I/O vs. normal
memory access on Apex devices have already been explicitly coded
From: Todd Poynor
Some explicit memory barriers in the page table code are not necessary,
either because:
(a) The barrier follows a non-relaxed MMIO access that already performs
a read or write memory barrier.
(b) The barrier follows DMA API calls for which the device-visible
effects of IOMMU
