[U-Boot] [Patch v2 1/2] common/board_f: Preserve global data for mpc85xx and mpc86xx

For powerpc SoCs (including mpc85xx, mpc86xx), global data is used for
initializing LAWs, before calling function baord_inti_f(). This data
should not be cleared later.

Change log
 v2: Instead of adding back gd init for all PPC, preserve gd for mpc85xx and mpc86xx.

 Note, need other maintainers to fix 83xx, 5xxx, 512x as I don't have boards to verify.
