Revert "OPP: Add dev_pm_opp_find_freq_exact_indexed()"

Browse Source 
This reverts commit 7baa59f83f which is
commit a5893928bb upstream.

It breaks the Android kernel abi and can be brought back in the future
in an abi-safe way if it is really needed.

* dev_pm_opp_find_freq_exact_indexed() - Search for an exact freq for the

* Return: matching *opp , else returns ERR_PTR in case of error and should be
* handled using IS_ERR. Error return values can be:
* EINVAL: for bad pointer
* ERANGE: no match found for search
* ENODEV: if device not found in list of registered devices
*
* The callers are required to call dev_pm_opp_put() for the returned OPP after
