s390: time: Provide read_boot_clock64() and read_persistent_clock64()
As part of addressing the "y2038 problem" for in-kernel uses,
this patch converts read_boot_clock() to read_boot_clock64()
and read_persistent_clock() to read_persistent_clock64() using
timespec64.
Rename some instances of 'timespec' to 'timespec64' in time.c and
related references
