ARM: dts: sama7g5ek: fix TXC pin configuration
TXC line is directly connected from the SoC to the KSZ9131 PHY. There is a transient state on this signal, before configuring it to RGMII, which leads to packet transmit being blocked. Keeping a pull-up when muxing this pin as function A (G0_TXCK) fixes the issue. Signed-off-by: Nicolas Ferre <nicolas.ferre@microchip.com>
