powerpc/embedded6xx: Add __init attribute to eligible functions

Some functions defined in 'arch/powerpc/platforms/embedded6xx' are
deserving of an `__init` macro attribute. These functions are only
called by other initialization functions and therefore should inherit
the attribute.
Also, change function declarations in header files to include `__init`.
