The CTE reception and sampling in connected mode was enabled with CONFIG_BT_CTLR_DF_CONN_CTE_REQ. This is a separate fearure tha can be enabled when CTE reqest procedure is disabled. What more the CONFIG_BT_CTLR_DF_CONN_CTE_REQ is dependent on CONFIG_BT_CTLR_DF_CONN_CTE_RX, not other way around. The commit adds separate Kconfig to provide such possibility. Also changes compilation guards for code related with the CTE reception and sampling. Signed-off-by: Piotr Pryga <piotr.pryga@nordicsemi.no>
