qcacmn: Store the threshold freq in regulatory

If a Radio supports 6G band channels, the ACS is expected to give
priority to a set of channels that are above a certain (threshold)
frequency.

Store the extracted threshold frequency from WMI into regulatory
component.

Add a new API reg_get_thresh_priority_freq to get the threshold
frequency received from the target.
