Subject: [PATCH 46/58] x86: arch/x86/kernel/irqinit.c: Add prototype for init_IRQ

arch/x86/kernel/irqinit.c defines an __init function init_IRQ, called
from init/main.c.  No header file prototypes init_IRQ, because
init/main.c tends to directly define prototypes for init functions it
calls, rather than including appropriate headers.  So, add a prototype
of init_IRQ to arch/x86/kernel/irqinit.c right above the definition, to
satisfy gcc (-Wmissing-prototypes) and Sparse (-Wdecl).

arch/x86/kernel/irqinit.c:118:116: warning: no previous prototype for ‘init_IRQ’ [-Wmissing-prototypes]
