Extend frequency configuration to handle 6 GHz channel 2

In hostapd_set_freq_params(), if center_segment0 is 2, call
ieee80211_chan_to_freq() with operating class 136 instead of 131.

This is needed because, channel 2 is an exception in the 6 GHz band. It
comes before channel 1 and is part of operating class 136.

Channels order in 6 GHz:
    2 (Operating Class 136)
    1   5   9 ....  (Operating Class 131)
