powerpc/kconfig: Kill PPC_MULTIPLATFORM
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 Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
