PM / devfreq: Remove the invalid description for get_target_freq
First of all, no_central_polling was removed since commit 7e6fdd4bad03 ("PM / devfreq: Core updates to support devices which can idle") Secondly, get_target_freq() is not only called only with update_devfreq() notified by OPP now, but also min/max freq qos notifier. So remove this invalid description now to avoid confusing. Signed-off-by: Dong Aisheng <aisheng.dong@nxp.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
