This converts the following to Kconfig: CONFIG_SYS_IMMR We do this by consolidating the SYS_IMMR options we have and providing defaults. We also, in the few places where M68K was also sharing code with these platforms, define it within the file to CONFIG_SYS_MBAR to match usage. This should be cleaned up longer term.
