Subject: [PATCH 08/16] xtensa: traps: add <linux/cpu.h> for function prototype

Use <linux/cpu.h> to provide the prototype for trap_init(), to prevent
a build warning:

arch/xtensa/kernel/traps.c:484:13: warning: no previous prototype for 'trap_init' [-Wmissing-prototypes]
  484 | void __init trap_init(void)
