configs: apalis-imx8x.h: define FEC_ENET_ENABLE_TXC_DELAY
We need a delay on RGMII TXC clock line by 2ns to accomodate to the
data-line edges. In the RGMII standard this has to be done by the MAC
for TXC and by the PHY for RXC.
fsl,rgmii_txc_dly that is used in linux-kernel is not implemented in
U-Boot so use the actual implemented define FEC_ENET_ENABLE_TXC_DELAY
RXC delay will be done by KSZ9131 PHY.
