should the input param be of type enum ath12k_supported_bw to better 
describe it?
should the function return type be enum rate_info_bw to better describe it?

change to use RATE_INFO_BW_20?

nit: remove 200ms from the comment. the value of the macro will be the 
actual value, and values in comments like this tend to get out of sync

Ramya removed the initialisation in commit:

640978f9fb1f wifi: ath12k: Fix typo and initializer in mac.c

But the unused field is still in struct ath12k_vif, I added that to todo
list.
