board: stm32mp1: move the function board_debug_uart_init in spl.c
Move the debug function board_debug_uart_init in spl.c as the debug_uart_init() function is called in arch_cpu_init() only for SPL and remove the board.c file. For TFABOOT, the UART TX pin configuration is done in TF-A. Signed-off-by:Patrick Delaunay <patrick.delaunay@st.com> Reviewed-by:
