Subject: [PATCH] parisc: time: Convert read_persistent_clock() to read_persistent_clock64()

The read_persistent_clock() uses a timespec, which is not year 2038 safe
on 32bit systems. On parisc architecture, we have implemented generic RTC
drivers that can be used to compensate the system suspend time, but the
RTC time can not represent the nanosecond resolution, so this patch just
converts to read_persistent_clock64() with timespec64.
