Subject: [PATCH] arch: *: remove '__init' for setup_profiling_timer()

Most of architectures not use '__init' for setup_profiling_timer(), so
need remove it, or can generate warning (e.g. arc with allmodconfig):

    MODPOST vmlinux.o
  WARNING: vmlinux.o(.text+0x3c682): Section mismatch in reference from the function write_profile() to the function .init.text:setup_profiling_timer()
  The function write_profile() references
  the function __init setup_profiling_timer().
  This is often because write_profile lacks a __init
  annotation or the annotation of setup_profiling_timer is wrong.
