653d227e9f MBO: Improve supported operating class generation
Previously, 2.4 GHz operating class 81 was not added for US due to not
all of the channels (1-13 in this operating class) being supported.
Still, this operating class is the main operating class in the global
table for 2.4 GHz and it is the only option for indicating support for
the 2.4 GHz band channels in US.

Change the supported operating class building rules to include all
operating classes for which at least one channel is enabled. In
addition, fix the 80, 80+80, and 160 MHz channel checks (checking the
center frequency channel was failing since it is not a valid 20 MHz
channel).

dd5999084e MBO: Parse MBO IE in BSS Transition Management Request frames
Add parsing of MBO IE in BSS Transition Management Request frames. If
the MBO IE includes the association retry delay attribute, do not try to
reconnect to the current BSS until the delay time is over.

If the MBO IE includes the cellular data connection preference attribute
or the transition rejection reason attribute, send a message to upper
layers with the data.
