[U-Boot] [PATCH 2/3] SPL: create Kconfig options for CONFIG_SPL_*_LOAD

[Fabien Parent]

In order to clean up the config headers and also to allow to easily
switch the boot device for some boards without having to modify the
config headers, it is better to move the options to Kconfig. This
commit move the CONFIG_SPL_*_LOAD options to Kconfig files.
