[PATCH 0/5] board: sl28: enable DM_SERIAL and lpuart support

[Michael Walle]

Enable DM_SERIAL for this board. For this to work, we first need to make
DM_SERIAL work on LS1028A SoCs, which just means we have to properly call
spl_early_init(). After this, clean up the board config by moving the
CONFIG_DM_* macros to Kconfig. Now we can switch to DM_SERIAL. As the last
patch, provide a configuration option to switch the output to the first
serial line on this board, which is not possible because we can enable
LPUART support (which needs DM_SERIAL).

Please note, the first patch is not really required but helps a lot in
debugging early startup on Layerscape SoCs.
