genirq/debugfs: Show debug information for all irq descriptors
Currently the debugfs shows only information about actively used interrupts
like /proc/irq/ does. That's fine for most cases, but not helpful when
internals of allocated, but unused interrupt descriptors have to
debugged. It's also useful to provide information about all descriptors so
leaks can be debugged in a simpler way.
Move the debugfs registration to the descriptor allocation code.
