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
