[PATCH v4 1/5] media: soc-camera: use icd->control instead of icd->pdev for reset()

icd->control is the sub device dev, i.e. i2c device.
icd->pdev is the soc camera device's device.

To be consitent with power() function, we will call reset() with
icd->control as well.

v3->v4:
  none

v2->v3:
  1. check whether icd->control is NULL or not.
