Subject: [PATCH 11/17] thermal: rockchip_thermal: enable/check sensor after
 its setup is finished

* Enable/check sensor explicitly in rockchip_thermal_probe() (also
  check sensor after doing chipset specific control operation).

* Remove superfluous second sensor enable/check attempt.

This driver may require some more fixing (probably IRQ should be
requested after ->control call).
