OMAP: omap_device: use read_persistent_clock() instead of getnstimeofday()
During suspend and resume, when omap_device deactivation and
activation is happening, the timekeeping subsystem has likely already
been suspended. Thus getnstimeofday() will fail and trigger a WARN().
Use read_persistent_clock() instead of getnstimeofday() to avoid this.
