powerpc/sysdev: Add __init attribute to eligible functions 



Some files functions in 'arch/powerpc/sysdev' 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`.
