[PATCH 2/3] ARM: dts: stm32: lxa-tac: change stdout-path baud rate from 9600 to 115200

[Ahmad Fatoum]

The default baud rate when none is specified is up to the DT consumer.

In the case of the Linux STM32 serial driver, it defaults to 9600 baud,
which differs from the 115200 baud that this board's barebox bootloader
configured.

This went unnoticed, because barebox automatically fixes up a console=
command-line option that looks like this on the LXA boards:

  console=ttySTM0,115200n8

This had precedence over the 9600 fallback baud rate.

But when EFI booting a kernel via GRUB, we run into this issue, because
the barebox-provided command-line is disregarded by GRUB.

Fix this by explicitly setting the baud rate to the correct 115200.
