[PATCH v3 09/10] change time types to new y2038 safe __kernel_* types

[Deepa Dinamani <deepa.kernel@gmail.com>]

Change over clock_settime, clock_gettime and clock_getres
syscalls to use __kernel_timespec times. This will enable
changing over of these syscalls to use new y2038 safe syscalls
when the architectures define the CONFIG_64BIT_TIME.
