Go over the IRQ subsystem source code (including irqchip drivers) and
fix common typos in comments.
No change in functionality intended.

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Most interrupt flow handlers do not use the irq argument. Those few
which use it can retrieve the irq number from the irq descriptor.
Remove the argument.
Search and replace was done with coccinelle and some extra helper
scripts around it. Thanks to Julia for her help!

The IRQCHIP_DECLARE macro moved to to 'include/linux/irqchip.h', so
the local irqchip.h became an empty shell, which solely includes
include/linux/irqchip.h
Include the global header in all irqchip drivers instead of the local
header, so we can remove it.

The num_ct argument of irq_alloc_domain_generic_chips() tells the core
code how many chip types (for different control flows,
e.g. edge/level) should be allocated. It does not control how many
generic chip instances are created because that's determined from the
irq domain size and the number of interrupts per chip.
The dw-apb init abuses the num_ct argument for allocating one or two
chip types depending on the number of interrupts. That's completely
wrong because the alternate type is never used.
This code was obviously never tested on a system which has more than
32 interrupts as that would have never worked due to the unitialized
second generic chip instance.
Hand in the proper num_ct=1 and fixup the chip initialization along
with the interrupt handler.

This patch adds in support for S2R for dw-apb-ictl irqchip driver.
We can used relaxed variants in the resume hook because there's no DMA
at all here, the device type memory attribute can ensure the operations
order and relaxed version imply compiler barrier.

The irq_chip_type instances have separate mask registers, so we need to
enable IRQ_GC_MASK_CACHE_PER_TYPE to actually handle separate mask registers.

There's no DMA at all, the device type memory attribute can ensure the
operations order and relaxed version imply compiler barrier, so we are safe
to use relaxed version to improve the performance a bit.

This adds an irqchip driver and corresponding devicetree binding for the
secondary interrupt controllers based on Synopsys DesignWare IP dw_apb_ictl.
