These patches enables Bluetooth functinalties for new Qualcomm
Bluetooth chip wnc3991. As this is latest chip with new features,
along with some common features to old chip "qcom,qcawcn3991-bt".
Major difference between old BT SoC's with WCN3991 is WCN3991 
will not send any VSE for the VSC instead is sends the data on CC
packet.

v2:
* updated review comments

Balakrishna Godavarthi (2):
  Bluetooth: btqca: Rename ROME specific variables to generic variables
  Bluetooth: hci_qca: Add support for Qualcomm Bluetooth SoC WCN3991

Variables which are named with rome are commonly used for all the
BT SoC's. Instead of continuing further, renamed them to generic
name.
