powerpc: minor cleanups for mpc86xx
* Remove duplicated cputable entry for 8641 (matches w/7448) * Removed __init from function prototypes in mpc86xx.h * Moved pci fixups into board specific code * Moved mpc86xx_exclude_device to generic mpc86xx pci code * Fixed sparse warnings in mpc86xx_smp.c * Removed board specific header include from asm-powerpc/mpc86xx.h Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
