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).
