Hearing Aid: set BLE phy to 2M if local and peer indicate PHY 2M support

Set the BLE phy to 2M if the BT controller and peer Hearing Aid device

Test: 1.Forget/Repair Hearing Aid device check whether phy is expected.
2.Disconnect/Reconnect Hearing Aid device check whether phy is expected.
3.HearingAid device power off/on, check whether phy is expected.
