530719b234 of/irq: of_irq.c needs to include linux/irq.h
It works on current architectures simply because asm/prom.h includes
it, but it broke when x86 turned on CONFIG_OF.

52f6537cb2 of/irq: remove references to NO_IRQ in drivers/of/platform.c
Instead of referencing NO_IRQ in platform.c, define some helper functions
in irq.c to call instead from platform.c.  Keep NO_IRQ usage local to
irq.c, and define NO_IRQ if not defined in headers.

7dc2e1134a of/irq: merge irq mapping code
Merge common irq mapping code between PowerPC and Microblaze.

This patch merges of_irq_find_parent(), of_irq_map_raw() and
of_irq_map_one().  The functions are dependent on one another, so all
three are merged in a single patch.  Other than cosmetic difference
(ie. DBG() vs. pr_debug()), the implementations are identical.

of_irq_to_resource() is also merged, but in this case the
implementations are different.  This patch drops the microblaze version
and uses the powerpc implementation unchanged.  The microblaze version
essentially open-coded irq_of_parse_and_map() which it does not need
to do.  Therefore the powerpc version is safe to adopt.

e387344499 of/irq: Move irq_of_parse_and_map() to common code
Merge common code between PowerPC and Microblaze.  SPARC implements
irq_of_parse_and_map(), but the implementation is different, so it
does not use this code.
