Controllers, supported by this driver, have two sets of registers:
* (main) interrupt registers control peripheral interrupt sources.
* device interrupt registers configure per-device (network interface)
interrupts and act as an extra stage before the main interrupt
registers.
In the driver unmask code, device trigger registers are used in the mask
calculation of the main interrupt sticky register, mixing two kinds of
registers.
Use the main interrupt trigger register instead.

Wherever possible, replace constructs that match either
generic_handle_irq(irq_find_mapping()) or
generic_handle_irq(irq_linear_revmap()) to a single call to
generic_handle_domain_irq().

This patch extends irqchip driver for oceleot to be used with an other
vcoreiii base platform: Luton.
For this platform there is a few differences:
- the interrupt must be enabled for the parent controller
- there is no trigger register needed to be managed

The Microsemi Ocelot SoC has a pretty simple IRQ controller in its ICPU
block. Add a driver for it.
