When the eTSEC is configured for TBI modes, all clocks are supplied from external sources to the relevant
eTSEC interface. In single-clock TBI mode, when TBICON[CLKSEL] = 1, a 125-MHz TBI receive clock
is supplied on the TSECn_RX_CLK pin (no receive clock is used on TSECn_TX_CLK in this mode,
whereas for the dual-clock mode this is the PMA1 receive clock). The 125-MHz transmit clock is applied
on the TSEC_GTX_CLK125 pin in all TBI modes.
