[PATCH] spl: Align device tree blob address at 8-byte boundary

[Bin Meng <bmeng.cn@gmail.com>]

Since libfdt v1.6.1, a new requirement on the device tree address via:

  commit 5e735860c478 ("libfdt: Check for 8-byte address alignment in fdt_ro_probe_()")

must be met that the device tree must be loaded in to memory at an
8-byte aligned address.
