d65b84a1d0 ARM: dts: at91: update flexcom defines using include file
Replace the number in the flexcom-mode property with the define from the
include file.
This corresponds to the approach in Linux kernel.

5dc68b07e7 ARM: dts: at91: sama7g5ek: enable pull-up for serial debug line
If the serial tx/rx are floating, it can happen that bogus characters
are detected on the line at boot time. This leads to U-boot accidentally
thinking someone pressed a key to stop autoboot, thus stopping booting process.
This can happen if the serial cable is not connected. There are hardware
pull-ups on the board connected to serial cable VBUS.
To solve this when the cable is not plugged, enable internal pull-ups as well
for the tx/rx lines.

aeaef07c51 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.
