    CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't
    really meaningful anymore. It was basically equivalent to PPC64 || 6xx.
    
    This removes it along with the following changes:
    
     - 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely
       on 6xx which is what they want anyway.
    
     - A new symbol, PPC_BOOK3S, is defined that represent compliance with
       the "Server" variant of the architecture. This is set when either 6xx
       or PPC64 is set and open the door for future BOOK3E 64-bit.
    
     - 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use
       PPC64 && PPC_BOOK3S
    
     - A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now
       used to control the use of prom_init.c
