[U-Boot] [PATCH v2] powerpc/mpc85xx: The end address of the bss in the SPL should be 4byte alignment

[ying.zhang at freescale.com]

From: Ying Zhang <b40530 at freescale.com>

There will clear the BSS in the function clear_bss(), the reset address of
the BSS started from the __bss_start, and increased by four-byte increments,
finally stoped depending on the adress is equal to the _bss_end. If the end
address __bss_end is not alignment to 4byte, it will be an infinite loop.

The end address of the bss should be 4byte aligned.

This patch is on top of the patch "powerpc/mpc85xx: support application
without resetvec segment in the linker script".
