As this seems to be a regression, please describe the failure case, and
how to reproduce it.
This patch adds the flag to identify the Intel legacy ROM products that
don't support WBS like WP and StP.
Please add, why the quirk is only for to 0x07dc and 0x0a2a, and how it
was tested.
Fixes: 3df4dfbec0f29 ("Bluetooth: btintel: Move hci quirks to setup routine")
