Subject: [PATCH] frv: Use read_persistent_clock64() instead of read_persistent_clock()

The struct timespec is not y2038 safe on 32bit systems, thus this patch
converts the read_persistent_clock() to read_persistent_clock64() with
using struct timespec64. We also use time64_t type to record system time
by converting the mktime() to mktime64() .
