Fix BLE with MT7668

- Some time between 4.4 and 4.19, Bluetooth stack starts to actually
query the HCI controller amount commands it supports, instead of
assuming support.
- The MT7668 firmware does not report back that it has support for a
variety of BLE related functions, like reading advertising data(!),
despite this working fine.
- Check against the hw_info field of the hci_dev, and manually set the
feature flags if we are an mt7668.
