x86: Convert x86_platform_ops to timespec64
The x86 platform operations are fairly isolated, so it's easy to change
them from using timespec to timespec64. It has been checked that all the
users and callers are safe, and there is only one critical function that is
broken beyond 2106:
pvclock_read_wallclock() uses a 32-bit number of seconds since the epoch
to communicate the boot time between host and guest in a virtual
environment. This will work until 2106, but fixing this is outside the
scope of this change, Add a comment at least.
