powerpc/85xx: Add PBL boot from SPI flash support on P4080DS
PBL(pre-boot loader): SPI flash used as RCW(Reset Configuration Word) and
PBI(pre-boot initialization) source, CPC(CoreNet Platform Cache) used as
1M SRAM where PBL will copy whole U-BOOT image to, U-boot can boot from
CPC after PBL completes RCW and PBI phases.
