[PATCH 06/16] xtensa: signal: include headers for function prototypes

[Randy Dunlap]

Add <asm/syscall.h> to satisfy the xtensa_rt_sigreturn() prototype
warning.
Add <asm/processor.h> to satisfy the do_notify_resume() prototype
warning.

arch/xtensa/kernel/signal.c:246:17: warning: no previous prototype for 'xtensa_rt_sigreturn' [-Wmissing-prototypes]
arch/xtensa/kernel/signal.c:525:6: warning: no previous prototype for 'do_notify_resume' [-Wmissing-prototypes]
  525 | void do_notify_resume(struct pt_regs *regs)
