can: etas_es58x: clean-up documentation of struct es58x_fd_tx_conf_msg
The documentation of struct es58x_fd_tx_conf_msg explains in details the different TDC parameters. However, those description are redundant with the documentation of struct can_tdc. Remove most of the description. Also, fixes a typo in the reference to the datasheet (E701 -> E70).
