IIO fixes for 4.0 set 4

A couple more IIO fixes.

* Fix check for HAS_IOMEM in the cc100001_adc driver to avoid build errors.
  Rather curiously it was ORed with Regulator and clock support.
* vf610 driver was trying to use an ADC clock outside the possible
  spec on some boards.  The driver assumed a fixed clock speed previously
  across all boards, but that is not true.  This fix ensures that the
  reported frequency is correct on all boards.
* The adis imu common code directly set the current trigger to the
  driver supplied one.  Unfortunately this didn't increase the use count
  leading to a double free via a particular path of changing the trigger
  then removing the driver.
