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.

e6d7961e5b microblaze: Fix IRQ entry/exit ftracing
Function traces on Microblaze don't include IRQ entry and exit arrows,
i.e.

 0)               |                            memcpy_toiovec() {
 0)   ==========> |
 0)               |                              do_IRQ() {
 ...
 0)   <========== |
 0) ! 5414.000 us |                            }

...because do_IRQ() doesn't have the proper attributes.

c6ba01a4c7 microblaze: Add irq_create_{of_,}mapping functions
Support function for PCI. We don't use any advance mapping mechanism
that's why implementation is simple.
