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)

In general this looks good to me, a few nits inside.

The 'driver'/'DRV' midfix is a bit misleading. WBS support is a device
capability, it's not something the driver supports or doesn't. Maybe
name it 'qca_capabilities' or similar.

Capabilities sounds good to me.

Thanks for the feedback.
