This adds a device tree binding for the VIC based on the of_irq_init()
support. This adds an irqdomain to the vic and always registers all
vics in the static vic array rather than for pm only to keep track of
the irq domain. struct irq_data::hwirq is used where appropriate rather
than runtime masking.
v3: - include linux/export.h for THIS_MODULE
v2: - use irq_domain_simple_ops
- remove stub implementation of vic_of_init for !CONFIG_OF
- Make VIC select IRQ_DOMAIN

The GIC support code is heavily using the fact that hardware
implementations are exposing banked registers. Unfortunately, it
looks like at least one GIC implementation (EXYNOS) offers both
the distributor and the CPU interfaces at different addresses,
depending on the CPU.
This problem is solved by allowing the distributor and CPU interface
addresses to be per-cpu variables for the platforms that require it.
The EXYNOS code is updated not to mess with the GIC internals while
handling interrupts, and struct gic_chip_data is back to being private.
The DT binding for the gic is updated to allow an optional "cpu-offset"
value, which is used to compute the various base addresses.
Finally, a new config option (GIC_NON_BANKED) is used to control this
feature, so the overhead is only present on kernels compiled with
support for EXYNOS.
Tested on Origen (EXYNOS4) and Panda (OMAP4).
