WCN3991 supports transparent WBS (host encoded mSBC). Add a flag to the
device match data to show WBS is supported.
This requires the matching firmware for WCN3991 in linux-firmware:
1a8b0dc00f77 (qca: Enable transparent WBS for WCN3991)

nit: the '_SUPPORTED' suffix seems somewhat redundant, given that this
is a capability (as 'CAP' indicates). Up to you if you want to keep it.
