Raag Jadav bcfb443557 pps: generators: tio: fix platform_set_drvdata() 
platform_set_drvdata() is setting a double pointer to struct pps_tio as
driver_data, which will point to the local stack of probe function instead
of intended data. Set driver_data correctly and fix illegal memory access
by its user.

 BUG: unable to handle page fault for address: ffffc9000117b738
 RIP: 0010:hrtimer_active+0x2b/0x60
 Call Trace:
  ? hrtimer_active+0x2b/0x60
  hrtimer_cancel+0x19/0x50
  pps_gen_tio_remove+0x1e/0x80 [pps_gen_tio]
