At present we do support allocating the bloblist but the Kconfig is a bit strange, since we still have to specify an address in that case. Partly this is because it is a pain to have CONFIG options that disappears when its dependency is enabled. It means that we must have #ifdefs in the code, either in the C code or header file.
Make use of IF_ENABLED_INT() and its friend to solve that problem, so we can separate out the location of bloblist into a choice. Put the address and size into variables so we can log the result.
Add the options for SPL as well, so we can use CONFIG_IS_ENABLED().
