irq: hide debug macros so they don't collide with others.

The file kernel/irq/debug.h temporarily defines P, PS, PD
and then undefines them.  However these names aren't really
"internal" enough, and collide with other more legit users
such as the ones in the xtensa arch, causing:

In file included from kernel/irq/internals.h:58:0,
                 from kernel/irq/irqdesc.c:18:
kernel/irq/debug.h:8:0: warning: "PS" redefined [enabled by default]
arch/xtensa/include/asm/regs.h:59:0: note: this is the location of the previous definition

Add a handful of underscores to do a better job of hiding these
temporary macros.
