parisc: time: Convert read_persistent_clock() to read_persistent_clock64()

Browse Source 
[ Upstream commit f76cdd00ef ]

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.
