genirq/debugfs: Print irqdomain flags as human-readable strings
Improve the readability of irqdomain debugging information in debugfs by
printing the flags field of domain files as human-readable strings instead
of a raw bitmask, which aligned with the existing style used for irqchip
flags in the irq debug files.
Before:
#cat :cpus:cpu@0:interrupt-controller
name: :cpus:cpu@0:interrupt-controller
size: 0
mapped: 2
flags: 0x00000003
After:
#cat :cpus:cpu@0:interrupt-controller
name: :cpus:cpu@0:interrupt-controller
size: 0
mapped: 3
flags: 0x00000003
IRQ_DOMAIN_FLAG_HIERARCHY
IRQ_DOMAIN_NAME_ALLOCATED
