firmware: ti_sci: rm: Add support for tx_tdtype parameter for tx channel
The system controller's resource manager have support for configuring the TDTYPE of TCHAN_CFG register on j721e. With this parameter the teardown completion can be controlled: TDTYPE == 0: Return without waiting for peer to complete the teardown TDTYPE == 1: Wait for peer to complete the teardown Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Reviewed-by: Tero Kristo <t-kristo@ti.com> Tested-by: Keerthy <j-keerthy@ti.com> Reviewed-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@oracle.com>
