rockchip: rk3188: add board_debug_uart_init() 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.

common: Move hang() to the same header as panic() At present panic() is in the vsprintf.h header file. That does not seem like an obvious choice for hang(), even though it relates to panic(). So let's put hang() in its own header. Signed-off-by: Simon Glass <sjg@chromium.org> [trini: Migrate a few more files] Signed-off-by: Tom Rini <trini@konsulko.com>

dm: core: Require users of devres to include the header At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Anatolij Gustschin <agust@denx.de>

rockchip: adding the missing "/" in entries of boot_devices Without the prefix, "same-as-spl" in `u-boot,spl-boot-order` will not work as expected. When board_boot_order() `spl-boot-order.c` meets "same-as-spl", it gets the conf by looking the boot_devices table by boot source, and parse the node by the conf with: node = fdt_path_offset(blob, conf); which will failed without the "/" indicating the path. Currently only entries of boot_devices in rk3399 have the "/" prefix. Therefore add the missing ones in other boards.
