[PATCH v3 4/4] Bluetooth: qca: Support more soc types for non-serdev devices

[Zijun Hu <quic_zijuhu@quicinc.com>]

For non-serdev devices which are derived from tool btattach, only
default soc type QCA_ROME is supported currently since there are no
way to get soc type from DT or ACPI, this change supports more soc
types by using user specified soc type for non-serdev devices.
