Add channel 144 (5720 MHz) into operating class conversion tables

Browse source 
Based on IEEE Std 802.11-2020 Table E-3 (Operating classes in Japan) and
Table E-4 (Global operating classes), we update channel 144 for those
corresponding operating classes.

The changes applicable to the global operating classes fixes an issue of
P2P GO not starting on channel 144 (frequency 5720 MHz) in cases where
the driver supports DFS operations.
