Since 0dba45864b ("arm: Init the debug UART") ,
the debug_uart_init is now called from crt.S
It's no longer required to call it from the board file.
With the current code, the banned <debug_uart> is printed twice:
<debug_uart>
<debug_uart>
U-Boot 2022.07-rc4-00089-gee3d158fa8 (Jun 08 2022 - 17:39:29 +0300)
Remove all calls from board_early_init_f .
