qcacld-3.0: Don't use Auto API to get Op class from freq

Use wlan_reg_freq_width_to_chan_op_class() instead of
wlan_reg_freq_width_to_chan_op_class_auto() to convert freq
to Operating class.
As the auto API forces the non-6Ghz channel to use the channel
map class. With auto API, in case of 6Ghz band, only those classes
specified in global operating class can be used

For OCV validation , always use global opclass as mandated by spec
