[U-Boot] [U-Boot, 04/10] rockchip: rk3188: add board_debug_uart_init()

[Philipp Tomsich]

> Use board_debug_uart_init() for UART iomux init instead of
> do it in board_init_f, and move the function to soc file so
> that we can find all the soc/board setting in soc file and
> use a common board file.
