HC_CAP_HDR_BT_EN uses a reserved HC_CAPABILITIES bit. Similarly, MODE_I3C_HDR_BT uses a MODE value reserved for I3C transfers, while MODE_I3C_Fm_FmP cannot be encoded in the 3-bit Command Descriptor MODE field. These definitions are currently unused, so there is no functional change. Remove them to avoid implying support for non-existent HCI features and to prevent future misuse.
