Subject: proc/stat: remove arch_idle_time()
Date: Wed, 5 Apr 2023 16:34:52 +0200
The last (only) architecture specific arch_idle_time() implementation was
removed with commit be76ea614460 ("s390/idle: remove arch_cpu_idle_time()
and corresponding code").
Therefore remove the now dead code in fs/proc/stat.c as well.
