am7xxx: update signature and documentation of am7xxx_set_power_mode() In the signature, rename the 'mode' parameter to 'power' in order to show better what it is about, after all in am7xxx_set_zoom_mode() the correspondent parameter has been called zoom. In the documentation tells about the new guesses about what the expected behavior after AM7XXX_POWER_OFF is.
