Add a new top-level config option so support booting an image stored in RAM. This allows to move the RAM boot support into a sparate file and having a single condition to compile that file.

The series has been build tested using buildman.

Enable booting of an image in RAM. The image can be preloaded orit can be loaded by SPL directly into RAM (e.g. using USB).config SPL_RAM_DEVICE bool "Support booting from preloaded image in RAM"
- depends on SPL
- depends on SPL_RAM_SUPPORT
default y if SPL_RAM_SUPPORT or if ... list of targets from SPL_RAM_SUPPORT, I'm not quite sure which makes more sense but I suspect the latter. Thanks!
