85xx: Ensure BSS segment isn't linked at address 0
When U-Boot is relocated from flash to RAM pointers are modified accordingly. However, pointers initialzed with NULL values should not be modified so that they maintain their intended NULL value. If the BSS segment is linked at address 0 its address will not be updated as necessary during relocation. This is a temporary workaround. The end goal is to add support to U-Boot to dynamically locate the BSS at an arbitrary address at runtime. When the ability to fixup the BSS inteligently is added, this workaround can be removed and the 85xx link script can put the BSS at a fixed address at link time.
