irqdomain: Let irq_domain_mapping display hierarchical domains
Hierarchical domains seem to be hard to grasp, and a number of
aspiring kernel hackers find them utterly discombobulating.
In order to ease their pain, let's make them appear in
/sys/kernel/debug/irq_domain_mapping, such as the following:
96 0x81808 MSI 0x (null) RADIX MSI
96+ 0x00063 GICv2m 0xffff8003ee116980 RADIX GICv2m
96+ 0x00063 GICv2 0xffff00000916bfd8 LINEAR GICv2
[output compressed to fit in a commit log]
This shows that IRQ96 is implemented by a stack of three domains,
the + sign indicating the stacking.
